Abstract: A head pressure relief assembly for relieving pressure in the head assembly of an air compressor may include an exhaust valve post formed in the head assembly and an exhaust valve assembly comprised of a flapper valve. An aperture may be formed through the exhaust valve post for venting the head assembly prior to start of the compressor assembly. The flapper valve is capable of engaging the exhaust valve post to close the aperture at least partially for preventing flow from the head assembly through the aperture during the compression stroke of the compressor assembly piston. A head pressure relief assembly may also include an aperture disposed in the head assembly, a connecting tube therefor, or a check valve.
Abstract: The present invention is directed to a generator including a cart-type fame assembly for transporting the generator. The generator of the present invention is mounted to a multi-segmented base frame assembly which forms a partial cage about the generator for protecting the generator while minimizing the overall weight of the apparatus. In additional embodiments, a generator bracket, for supporting an alternator, is implemented to provide a convenient and economical mounting for a pair of wheels.
Abstract: A surface cleaner for assemblies having a spray nozzle such as pressure washers, spray wands, spray lances, and the like. The surface cleaner includes a guide having wheels in line with the spray nozzle for substantially maintaining the distance from the spray nozzle to a surface through a variety of angles assumed by the spray wand or the like. In exemplary embodiments, the guide is capable of being moved up and down the spray lance or the like for control of the cleaning force, and a set of markings may be provided on the guide, the spray lance, or the like for indicating the appropriate distance for the spray nozzle from many different surfaces. Additionally, the guide allows for one handed operation of the spray wand assembly.
Abstract: A method for manufacturing an air compressor assembly including, between a tank welding step and a final assembling step, a step of submerging a welded tank into a dip tank that contains cooling liquid treated with a corrosion inhibitor. In a preferred embodiment, in the submerging step, all air access ports of the welded tank are open to allow the cooling liquid to coat both the inside and outside surfaces of the air tank to maximize corrosion inhibitor protection and increase tank cooling rate. The method for manufacturing an air compressor assembly according to the present invention may be used in manufacturing air compressor assemblies in various styles.

Abstract: A deformable wedge clamp assembly includes a body having first and second apertures formed therein, the first aperture being suitable for receiving a fastener and the second aperture being suitable for receiving a member to which the body is to be attached and a wedge assembly disposed in the body adjacent to the first and second apertures, wherein insertion of a fastener into the first aperture is capable of deforming the body for moving the wedge assembly against a member received in the first aperture to clamp the body to the member.
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 a piston assembly. The straps communicate the rectilinear motion of the eccentric assembly to the piston assembly, reciprocating the piston assembly to pump the liquid.
