Appl. No.:

10/200675

Inventors:

Randolph L. Maiville - Onondaga MI, US
William T. Flynn - Horton MI, US

Assignee:

Eaton Corporation - Cleveland OH

International Classification:

F16K051/00
F16L029/00
F16L037/28

US Classification:

2511494, 2511496, 251353, 251354, 7386384

Abstract:

A valve for connecting a fluid sampling device to a fluid source is provided that includes a body adapted to be secured to the fluid source and a valve member moveably disposed within the body. The body includes a coupling interface configured to sealingly mate with the sampling device. The valve member is actuated by the sampling device during attachment of the sampling device to the valve body. The sampling device actuated valve member is moveable between a first position in which a flow path between the fluid source and the sampling device is closed and a second position in which the flow path between the fluid source and the sampling device is open. When the fluid flow path is open, the sampling device can withdraw a fluid sample for inspection and return the fluid sample to the fluid source without exposing the fluid to the surrounding environment.

International Classification:

F16L 5500

US Classification:

285119

Abstract:

A low flow resistant dry break fluid coupling suitable for military and industrial refueling applications wherein the coupling is connected to a male adapter by radially displaceable detents operated by an axially movable locking sleeve. The coupling including a valve having a manual actuating handle which includes locking sleeve interference structure preventing the locking sleeve from being displaced to the adapter release position while the valve is in the open position. Additionally, electric switch structure mounted upon the coupling body permits gloved actuation to control a fluid pump.

Assignee:

Aeroquip Corporation - Maumee OH

International Classification:

F16K 3708
F16K 2500

US Classification:

13761406

Abstract:

A ball valve type fluid coupling having identical interconnectable parts characterized by low fluid spillage during disconnection. The rotatable ball valve is axially displaceable by cam structure along the flow passage as the valve is rotated between open and closed positons which prevents the valve from passing through the plane of the coupling connection end during valve operation and the valve exterior surface includes a flat coupling connection end sealing surface substantially coplanar to the coupling connection end when the valve is closed to reduce trapping fluid and spillage.

Assignee:

Aeroquip Corporation - Jackson MI

International Classification:

F16K 3160

US Classification:

13761405

Abstract:

A security and safety latch system for fluid couplings particularly for fluid couplings utilizing rotatable valves wherein connection and disconnection of the coupling parts is by relative rotation of the parts and the valves are rotated between open and closed positions by exterior manually operated handles. The coupling parts and the valve handles are provided with interfering surfaces which prevent the parts from being relatively rotated and disconnected until both coupling valves are closed. Further, the valve handles are provided with security latches which permit the handles to be locked in the closed position, and prevent the valve handles from being locked in the valve open position.

International Classification:

F16L 3728

US Classification:

13761405

Abstract:

A no-spill fluid security system for couplings for use with fluids producing environmental impact wherein the coupling permits unidirectional flow for consumer use and bidirectional flow to permit the refilling of containers with specially designed mating coupling parts. The primary coupling part includes a valve located adjacent the primary part end to prevent spillage and a normally operative check valve prevents fluid flow into the primary coupling part while a secondary coupling part of special construction opens the normally closed check valve permitting unidirectional flow through the primary part. Pressure relief means are incorporated into the primary part to permit trapped fluids within an uncoupled primary part to be bled into the associated receptacle upon a predetermined pressure existing to prevent spillage.

Inventors:

Randolph L. Maiville - Onondaga MI

Assignee:

Aeroquip Corporation - Jackson MI

International Classification:

F16L 3500

US Classification:

285 2

Abstract:

A frangible, circumferentially contractible clamp operated by a band constricting actuator for securing a pair of flange end pipe members in aligned end-to-end relation. The clamp includes a band consisting of retainer halves which are fastened together by frangible fasteners to form an envelope adapted to embrace and secure the aligned flanges together upon tightening of the actuator. Upon the associated pipes being subjected to exceptional tensile or bending forces, the fasteners will fracture permitting the retainer halves to separate to allow the flanges to separate and prevent the pipes from being damaged.

Randolph L. Maiville - Onondaga MI, US

International Classification:

F16L 29/02
F16L 57/04

Abstract:

A self-sealing end fitting includes a valve, an adaptor, and a connector. The valve may define a longitudinal axis and may include a first end portion, a second end portion, a flange disposed therebetween, and a central bore. The adaptor may have a first end portion surrounding at least the second end portion of the valve, and the connector may surround at least the first end portion of the valve. A portion of the connector, a portion of the flange, and a portion of the first end portion of the adaptor may define a pocket. The valve may be configured to move axially relative to the adaptor. In embodiments, a sealing surface of the flange may contact a corresponding sealing surface of the first end portion of the adaptor to form a first seal within the pocket, and the first seal may comprise a metal-to-metal seal.
