Abstract: An air compressor assembly having an air tank which, during air usage, continuously discharges condensate accumulated in the air tank into the compressed air being released. The air tank has an air outlet port at its wall, through which compressed air and condensate are released for use in air powered tools during air usage.

Abstract: An air compressor assembly having an unpainted air tank that is enclosed in a shroud. The air tank may be made of metal, plastic, or the like. In a preferred embodiment, the shroud is made of plastic. The shroud may also be made of metal or the like. The air compressor assembly according to the present invention may be formed in various styles, including a portable type air compressor assembly, a “pancake” type air compressor assembly, a “hot-dog” type air compressor assembly, a vertical “hot-dog” type air compressor assembly, a vertical stationary type air compressor assembly, a “double hot-dog” type air compressor assembly, and the like.

Abstract: A manifold assembly is provided for controlling and distributing compressed air from an air compressor to one or more air powered tools. The manifold assembly may be attached directly to the air compressor, or, alternately, removed from the air compressor and coupled thereto via an air conduit, e.g., an air hose or the like, so that the manifold assembly can be used at locations remote from the air compressor.

Abstract: A two stage reciprocating piston oil free air compressor having an improved service interval. In a first stage, a first wobble piston is reciprocated in a first cylinder to compress ambient air to an intermediate pressure. In a second stage a second wobble piston is reciprocated in a second cylinder to compress the intermediate pressure air to a desired high pressure. Each wobble piston is provided with a seal which seals to the adjacent cylinder walls as the piston reciprocates and rocks. The stroke of the higher pressure second stage piston is less than the stroke of the lower pressure first stage piston to increase the operating life of the second seal, preferably to substantially the same operating life as the first seal.

Abstract: A towing vehicle and towed attached trailer connected using a ridged non-pivoting connection. The connection can be released by the user as desired to use the towing vehicle as a separate independent vehicle and reconnected as needed for towing of the trailer. The driving wheels of the towing vehicle are the front wheels. After the trailer is connected to the towing vehicle, the rear wheels of the towing vehicle are retracted vertically off of the ground shifting the combined weight of the vehicle and trailer to the front wheels of the vehicle and to the trailer wheels.

Abstract: An improved wobble piston and seal assembly for an oil free air compressor. The piston has a seal support surface which is provided with an upwardly directed curve adjacent its perimeter. A flat annular seal is secured to the piston to be supported by the support surface. The curve imparts a limited bend to the seal adjacent the perimeter of the piston. The piston and seal are then inserted into a cylinder which increases the bend to substantially 90°. The region of the bend in the seal adjacent the top of the piston is supported by the curved top to reduce flexing during operation at high air pressures. By preventing a reduction in the bend radius at high air pressures, stress in the seal at the bend is reduced, permitting use of a harder more durable seal material.
