摘要： The object of the present invention is to offer an electric type swash plate compressor which is compact and reduced in weight and lightened, and which can efficiently cool down a motor chamber and a crank chamber. The compressor has an electric motor and a swash plate, which are respectively accommodated in the motor chamber and the crank chamber. In the compressor a communication route, which communicates a part except the discharge chamber communicating with an external refrigerant circuit in an inner refrigerant circuit within an outer casing with the motor chamber, is formed. The communication route is formed so as to pass through the crank chamber, and the refrigerant in lower temperature and lower pressure than discharge refrigerant is supplied into the motor chamber and the crank chamber. Accordingly, the improvement of cooling efficiency and the reduction of pressure resisting strength of the casing can be performed.

摘要： A single-headed piston (22) is accommodated within each of a plurality of cylinder bores (13) formed on a cylinder block (13). Shoes (23) are disposed between a swash plate (11) and each single-headed piston (22). The rotation force of the swash plate (11) is transmitted to the single-headed piston (22) via the shoes (23). Each single-headed piston (22) makes a reciprocating motion within the cylinder bore (131) accompanied by the rotation of the swash plate (11). A rotary shaft (16) fixed to the swash plate (11) is driven by a motor (21).

摘要： A motor-driven compressor performs suction, compression, and discharge of refrigerant. The compressor has four cylinder bores and four pistons. A swash plate is integrally rotated with a drive shaft. A transmission mechanism transmits rotation of the swash plate to the pistons. The ratio of the discharge pressure to the suction pressure when the discharge displacement of the compressor is maximum, that is, the compression ratio, is in a range of 2 to 4.5. The compressor is constructed to permit the size of the motor to be minimized.

A valve plate provided in the case includes suction ports and discharge ports. A plurality of bores are provided at predetermined intervals about the axis of the shaft. Pistons are housed in the bores and compress refrigerant by reciprocating in accordance with the rotation of the shaft. An intermediate chamber connects a discharge port with a suction port. The refrigerant is compressed in stages by passing through a plurality of bores via the intermediate chamber. Compression chambers are defined between the pistons and the valve plate. A communication passage is provided for setting the pressures acting on the rear faces of the pistons to an intermediate pressure between the suction pressure and the discharge pressure.

摘要： Scroll compressors are taught that include an outer peripheral portion (23) of a movable scroll member (20) disposed opposite of an end face (13) of a stationary scroll member (10). At least one end portion (20, 23) has a shape that prevents contact when the movable scroll member (20) bends or deforms under high pressure. The contact avoiding shape or structure may be, for example, a tapered portion, a recessed portion or a step shaped portion.

摘要： In a reciprocating compressor, an adequate lubricating effect is ensured for a sliding surface between a piston and a cylinder bore, and the leakage of a refrigerant for discharge is prevented. After a lubricating oil mixed within the refrigerant is separated by an oil separator 23 on a discharge side, the separated lubricating oil is guided via an oil supply hole 29 in a cylinder block 1 to the sliding surface between the cylinder bore 12 and the piston 13 that reciprocates within the cylinder bore 12 thereof in order to lubricate the surface. In this reciprocating compressor, the intermediate axial portion of the outer circumference of the piston 13 has a small diameter in order to define an oil sump 30. The oil sump 30 is configured so as not to directly communicate with a drive chamber 7, and oil always collects within the oil sump 30.
