Actuator Having External Load Supporting Member
view source
US Patent:

7343846, Mar 18, 2008
Filed:

Mar 9, 2004
Appl. No.:

10/548449
Inventors:

Frantz D. Stanford - Madison WI, US
Jesus Salvador Gonzalez Sanz - Guadarrama, ES
Bruce Edwin Knuth - Marshall WI, US
Assignee:

Actuant Corporation - Glendale WI
International Classification:

F15B 15/26
B66F 3/24
US Classification:

92 23, 92 18
Abstract:

A hydraulic actuator is provided for supporting a load. The actuator includes a cylinder, a lower end closed by a base, and an annular side wall connected between the base and the upper wall. A piston is disposed partially within the cylinder, and includes a rod extending through the upper end of the cylinder, and a piston head that defines a hydraulic chamber with the base. A cylinder chamber is disposed between the base and the piston head and communicates with a fluid source and a fluid return to correspondingly extend and retract the piston. A support member is connected to the cylinder wall, and can be raised to support a tilt saddle member between the piston rod and the load after the piston has been extended.

US Patent:

8430122, Apr 30, 2013
Filed:

Aug 28, 2009
Appl. No.:

12/549473
Inventors:

Bruce E. Knuth - Oconomowoc WI, US
Assignee:

Helgesen Design Services, LLC - Hartford WI
International Classification:

B01D 21/00
US Classification:

137546, 137563, 210299
Abstract:

A hydraulic storage tank is provided. The hydraulic storage tank includes a storage tank, a return flow filtration chamber, a contaminant containment chamber (CCC) and a tube connecting the return flow filtration chamber with the CCC. The storage tank defines a reservoir for storing hydraulic fluid. The return flow filtration chamber is configured to house a return flow filter. The CCC includes a boundary wall bounding a cavity and a CCC outlet fluidly communicating the cavity with the reservoir. The CCC outlet is radially inward from the boundary wall. The tube defines a discharge passage fluidly connecting the filtration chamber with the cavity of the CCC and includes an inlet in fluid communication with the filtration chamber and an outlet in fluid communication with the CCC. The outlet of the tube directs fluid in angular direction about an axis defined by the contaminant containment chamber outlet.

Fluid Storage Tank Configured To Remove Entrained Air From Fluid

US Patent:

8491707, Jul 23, 2013
Filed:

May 23, 2011
Appl. No.:

13/113661
Inventors:

Bruce E. Knuth - Oconomowoc WI, US
Assignee:

Helgesen Design Services, LLC - Hartford WI
International Classification:

B01D 45/00
US Classification:

95267, 96155, 96204, 96215, 96189, 96220, 137 1, 137574, 137544, 220501, 60453
Abstract:

A fluid storage tank including an entrained air removal mechanism is provided. The entrained air removal mechanism assists in consolidating small air bubbles entrained within the fluid into larger bubbles such that the air bubbles have sufficient buoyancy to escape the fluid flow. The entrained air removal mechanism may be in the form of a plurality of saw toothed slots communicating different chambers within the fluid storage tank. The fluid storage tank can also be configured to direct fluid flow towards the sidewalls of the fluid storage tank as the fluid transitions from one chamber to another to promote heat transfer out of the fluid storage tank and to avoid the fluid within the tank acting as a thermal insulator.

Air Driven Hydraulic Pump

US Patent:

8496449, Jul 30, 2013
Filed:

Nov 21, 2007
Appl. No.:

12/515221
Inventors:

Bruce E. Knuth - Marshall WI, US
Kay Lap Gilbert Chan - Madison WI, US
Theo H. H. Den Ridder - Oosterhout, NL
Frantz D. Stanford - Monona WI, US
Roger R. Pili - Madison WI, US
Assignee:

Actuant Corporation - Mchomonee Falls WI
International Classification:

F04B 35/00
US Classification:

417375, 417382, 417441, 417903
Abstract:

A rotary air motor driven hydraulic pump has separate pressure and return actuators and first and second stage eccentric driven pistons 180 degrees out of phase and driven by the motor through a gear reduction unit. The pressure and return actuators are on/off/proportional valves and the pump has two pressure relief valves with one adjustable from outside of the pump for a user to set a pressure limit of the pump. Above a certain output pressure limit, a bypass valve shunts flow in excess of that needed to precharge the second stage compression chamber from the first stage piston to an elastic reservoir from which the hydraulic fluid pumped by the pump is drawn. To make the pump stall at a certain output pressure, a pressure limiting valve can be used that cuts off the air supply to the pump at the desired output pressure.

Variable Speed Hydraulic Pump

US Patent:

20030206805, Nov 6, 2003
Filed:

Mar 12, 2003
Appl. No.:

10/257302
Inventors:

Michael Bishop - Madison WI, US
Roger Pili - Madison WI, US
Bruce Knuth - Marshall WI, US
Moe Barani - Radford VA, US
Ron Flanary - Blacksburg VA, US
Laurentius Mentik - Haaksbergen, NL
George Steber - Mequon WI, US
Martin Piedl - Blacksburg VA, US
International Classification:

F04B049/06
US Classification:

417/044200, 417/326000, 417/199100
Abstract:

The invention provides a variable speed hydraulic pump designed to operate at a maximum horsepower throughout its pressure range by adjusting motor speed according to motor load parameters. In particular, the variable speed hydraulic pump includes a hydraulic pump unit coupled to a variable speed electric motor by a drive unit and to a hydraulic fluid tank for pressurizing and pumping hydraulic fluid when operated by the motor. A motor controller is electrically connected to the motor to supply drive signals to the motor based on electrical characteristics of the drive signals which are dependent on the load exerted on the motor. Suction from the load is provided by both the main pump and a bidirectional supercharging pump by reversing the direction of the motor and shifting a 4/3 valve to connect the main pump inlet to the load and its outlet to tank. In addition, the controller reduces the motor speed at the maximum rated pressure to just maintain the pressure, to reduce the amount of fluid pumped through the maximum pressure relief valve.

Gradual Release Pressurizing Valve For Fluid Storage Tank Breather And Breather Including Same

US Patent:

20100065565, Mar 18, 2010
Filed:

Sep 18, 2009
Appl. No.:

12/562592
Inventors:

Bruce E. Knuth - Oconomowoc WI, US
Robert E. Broman - Mequon WI, US
Assignee:

Helgesen Design Services, LLC - Hartford WI
International Classification:

B65D 90/32
F16K 1/52
US Classification:

220 891, 251205, 251336
Abstract:

A breather for a fluid storage tank, a storage tank incorporating same, and a method of releasing pressure in a fluid storage tank is provided. The present invention permits graduated release of pressure within the storage tank by allowing for varied flow rates of air out of the storage tank. In one embodiment, a valve assembly is provided that includes a valve member that has a graduated release feature that adjusts the size of a gap though the valve assembly formed between the valve member and a corresponding valve seat.

Hydro-Pneumatic System With Pressure Limiting Valve

US Patent:

20100104456, Apr 29, 2010
Filed:

Oct 25, 2007
Appl. No.:

12/446611
Inventors:

Frantz D. Stanford - Monona WI, US
Bruce E. Knuth - Marshall WI, US
Kay Lap Gilbert - Madison WI, US
International Classification:

F04B 17/00
F16K 15/00
US Classification:

417375, 137535
Abstract:

A hydro-pneumatic system has an air powered motor driving a hydraulic pump with a pressure limiting valve that turns off air flow to the air motor when a hydraulic pressure output by the pump at a sense port of the valve reaches a certain limit. A valve element of the valve has spring, hydraulic and pneumatic sections, with an unbalanced area of the hydraulic section in a sealed pressure chamber of a cartridge that is part of the valve housing. The pneumatic section extends out one end of the cartridge to fill a bore between the air inlet and outlet ports when the pneumatic section is extended, and allow air to pass when it is retracted.
