Filed:

Aug 14, 2000

Appl. No.:

09/639572

Inventors:

Shane Dexter - Humboldt TN
Allen Palmer - Lexington TN
Mark Wood - Jackson TN

Assignee:

DeVilbiss Air Power Company - Jackson TN

International Classification:

F01B 700

US Classification:

92150

Abstract:

An apparatus is described for capturing a bearing assembly in a device such as a high pressure pump or the like so that undesired pre-load within the bearing assembly is substantially reduced or eliminated. The apparatus is comprised of a fastener for capturing the bearing assembly by securing the bearing assembly to the shaft of the pumps eccentric assembly. A collet is disposed in the bearing assembly around the fastener. The fastener includes a tapered section for at least partially expanding the collet so that the collet engages the bearing assembly capturing the bearing assembly and controlling the amount of pre-load placed thereon.

International Classification:

F07B 4900

US Classification:

417299, 417307, 417 30

Abstract:

A high pressure pump suitable for use in devices such as pressure washers or the like is disclosed wherein the pumps head assembly includes an integral start valve for allowing the fluid through the head assembly so the engine may be more easily started. When the pump reaches a predetermined rate of flow of the fluid, the start valve assembly closes to circulate the fluid through said pump assembly.

International Classification:

F01B 700

US Classification:

92150, 92137

Abstract:

An oilless high pressure pump suitable for use in devices such as pressure washers and the like is described. The pump includes an eccentric assembly suitable for converting rotary motion of a rotating shaft to rectilinear motion. One or more straps couple the eccentric assembly to the pumps piston assembly. The straps communicate the rectilinear motion of the eccentric assembly to the piston assembly for reciprocating the pumps pistons to pump the liquid.

International Classification:

F04B 3500

US Classification:

417360

Abstract:

A pump for a pressure washer. The pump includes a cam housing, a piston assembly disposed within the cam housing, a rotary shaft assembly disposed within the cam housing, a journal plate attached to the cam housing, a head assembly attached to journal plate and valve assembly operatively connected to the head assembly. The rotary shaft assembly includes a cam shaft, a vertically-extending oil tube partially disposed within a central portion of the cam shaft, a cam threaded onto the cam shaft and a thrust washer positioned adjacent the threaded cam. The piston assembly includes a plurality of pistons, preferably three, in mating contact with the thrust washer. Each piston includes a piston spring cap at one end, a spring disposed over the piston and engaging the piston spring cap, and a seal retainer having a low pressure seal at one end and a high pressure seal at the other end. The seal retainer includes an opening between the low pressure seal and the high pressure seal such that fluid passing through the high pressure seal is captured by the low pressure seal for recycling back into the head assembly. The head assembly, in combination with the valve assembly, forms a castellated assembly of a plurality of towers, preferably three, one for each piston.
