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.

Assignee:

DeVilbiss Air Power Company - Jackson TN

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.

US Classification:

417568, 417571, 137512

Abstract:

A pressure washer pump generally includes a pump housing that defines a cavity, an opening into the cavity and a bottom of the cavity generally opposite the opening. A valve assembly is disposed in the cavity through the opening. The valve assembly includes a cage member that contains a first valve mechanism. A plug member is received in the opening to fluidly seal the cavity of the pump housing. A compliant member is disposed between the plug member and the cage member. The cage member is disposed between the compliant member and the bottom of the cavity and spaced from the plug member.
