摘要： An engine includes a cylinder system, a driving system including a piston and a crankshaft, a power generating system and a cooling system. The power generating system is disposed on a side of the driving system and includes a generator and a counterweight. The generator includes a main body and a rotor pivotally disposed within the main body. The cooling system is disposed on an opposite side of the driving system and includes a first water pump in fluid communication with the cylinder system. An outline of the rotor is projected along the crankshaft to form a first projecting zone. Projections of the first water pump and the driving system along the crankshaft overlap the first projecting zone.

摘要： A hydraulic pump and double-acting air motor therefor including means for controlling the inlet and exhaust of air to and from the opposite sides of the piston in the air cylinder. A pilot valve operated by the air piston controls one operating valve for the cylinder and a pilot relay valve. The pilot relay valve controls another operating valve which is in reverse phase with respect to the first-operating valve. The piston-operated pilot valve has a snap action feature so that the pilot valve, the pilot relay valve and the operating valves all reverse condition abruptly with a minimum dwell to provide a smoother power transmission. Also a muffler which inhibits ice formation is operatively associated with the operating valves for muffling the noise of the air being exhausted from the air cylinder through the operating valves with minimal accumulation of ice.

摘要： A positive displacement pump is provided having a housing, a plurality of pistons and an eccentric drive element rotatably mounted about an axis on the housing. A rigid compression member connected to each of the pistons is reciprocatably moveable with the pistons relative to the housing. At least one tension member is provided, connected between each of the pistons and the eccentric drive element at a point displaced from the axis. The tension member is permanently maintained in tension so as to continuously exert force radially inwardly on each of the pistons and to cause each of the pistons to continuously exert radially inward force on the compression member to permanently maintain the compression member in compression. The plurality of pistons preferably includes one or more pairs of pistons with each piston of the pair linked together by the compression element and reciprocates each in synchronism and 180.degree. out of phase with the other. The tension member preferably includes a transversely flexible elongated element connected at an inner end to the eccentric drive element at the point displaced from the axis and linked at an outer end to at least one of the pistons. The tension member preferably also includes a plurality of transversely flexible elongated elements, each connected at an inner end to the eccentric drive element at the point displaced from the axis and each linked at an outer end to one of the pistons.

摘要： A double acting hydraulic pump and air motor therefor including means for controlling the inlet and exhaust of air to and from the opposite sides of the piston in the air cylinder. The pump has a stepped diameter housing including an upper pump cylinder defining an outlet chamber for liquid and a lower pump cylinder received within the upper pump cylinder and defining an inlet chamber for liquid. A pump piston reciprocates in the two cylinders and is slidably received in two axially spaced stationary packing sleeves having a resilient spacer sleeve interposed axially therebetween. The spacer sleeve is formed of metal sheet adapted to deflect resiliently under load. The upper end of the upper pump cylinder is received within a recess in the lower end of the air motor housing. A retainer plate connected to the lower end of the air motor housing is provided with an opening to allow passage of the upper end of the upper pump cylinder and a pair of radially extending ears thereon. The pump housing is rotatable about its own longitudinal axis to align or misalign the ears and the opening and retain the pump housing to or release it from the motor housing.
