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 pump's piston assembly. The straps communicate the rectilinear motion of the eccentric assembly to the piston assembly for reciprocating the pump's pistons to pump the liquid.
Abstract: The present invention discloses an apparatus and method for protecting a condensate removal device from damage that may be caused when the condensate removal device comes into contact with foreign objects. The present invention discloses placing a shield around the condensate removal device to help prevent the condensate removal device from coming into contact with any foreign object. The present invention also discloses placing a removable cap around the condensate removal device and a condensate removal device that may recess within a mounting assembly.
Abstract: A high pressure pump suitable for use in devices such as pressure washers or the like is disclosed wherein the pump's 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.
Abstract: A turret assembly for mounting a plurality of spray nozzles on a pressure washer wand to facilitate changing the spray pattern. A female quick connect connector is mounted on the fluid discharge end of the wand to extend on an axis. Each nozzle is provided with a male connector adapted to be releasably locked in the female connector. The turret is mounted both for rotation on the wand about an axis and axial for movement. A spring urges the turret and nozzles away from the female connector. As the turret is rotated, the different nozzles can be moved into alignment with the female connector on the wand end. Once a selected nozzle is aligned with the female connector and the turret is moved against the spring force and the selected nozzle is releasably locked to the female connector. The nozzles can be quickly changed without risk of loss of the nozzles.
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 pump's 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.
