摘要： A swashplate type variable-displacement compressor includes a compressor housing defining therein a crank chamber, a refrigerant suction chamber, a refrigerant discharge chamber, and a low-pressure refrigerant passage connected to an evaporator outlet, and a pressure regulator. The pressure regulator controls the amount of low-pressure refrigerant gas flowing into the refrigerant suction chamber by regulating a differential pressure between the pressure in the refrigerant suction chamber and the pressure in the crank chamber. The pressure regulator is comprised of a flow control valve including a first spring-loaded, normally-closed spool valve and a pressure chamber accumulating the working pressure used to force the spool valve toward its fully-opened position, and a flow control valve actuating mechanism including a communication passage through which the refrigerant discharge chamber is communicated with the pressure chamber, a second spring-loaded, normally-closed pilot valve provided in the communication passage, and an electromagnetic solenoid controlling the opening of the pilot valve so that the opening increases with an increase in exciting current supplied to the solenoid. The pilot valve serves to introduce high-pressure refrigerant gas in the refrigerant discharge chamber into the pressure chamber as the working pressure with the opening controlled by the solenoid.

摘要： A device includes a power-transmission pulley rotatably mounted on an automotive accessory housing, a drive plate fixedly connected to a rotating shaft of the accessory, and shear pins which connect the pulley and the drive plate. The shear pins each have a notched portion and a flanged portion which is offset from the notched portion and which is sandwiched between the pulley and the drive plate. The diameter of shear-pin insertion holes formed in the drive plate is larger than the shear pins which are fixedly connected to the pulley. The shear pins are fixedly connected to the drive plate.

摘要： A swash plate type variable displacement compressor for refrigerant in a refrigeration cycle of an air conditioning system for an automotive vehicle. The compressor comprises a drive shaft around which a journal is movably disposed around so as to be rotatable with the drive shaft. The journal has a generally cylindrical boss section which has an external thread portion, and a flange section. A swash plate is provided for converting a rotational motion of the drive shaft into a linear motion of the pistons. The swash plate is fixedly mounted on the boss section of the journal and has an internal thread portion which is engaged with the external thread portion of the boss section. The swash plate includes a generally cylindrical thick central section having the internal thread portion, and a peripheral section integral with the central section and having an axial dimension smaller than the central section. A plurality of tool engaging grooves are formed at least in the central section and located on a first surface of the swash plate. The tool engaging grooves are located along a circumference concentric with a central bore of the central section. Additionally, a plurality of seat projections are formed on a second surface of the swash plate which second surface is opposite to the first surface, each seat projection projecting in a direction away from the second surface. The seat projections are located respectively corresponding to and at back sides of the tool engaging grooves. Each seat projection is to be in contact with the flange section of the journal.

摘要： A compressor is disclosed having a gas extraction passage, internally formed in a drive shaft and continuously communicating with a crank chamber and a suction chamber, that has an inlet portion, to be exposed to the crank chamber, is formed in the drive shaft in a radial direction. As a result, mist-like oil accompanied by blow-by gas tending to flow into the gas extraction passage initially impinges upon and adheres to an inner peripheral surface of the inlet portion of the gas extraction passage due to rotational movement of the drive shaft. Namely, oil separation (gas-liquid separation) occurs at the inlet portion of the gas extraction passage. Then, oil separated from the blow-by gas at the inlet portion of the gas extraction passage is forcibly returned to the crank chamber due to a centrifugal force caused by rotational movement of the drive shaft. Accordingly, the compressor has a structure in which oil accompanied by blow-by gas is hard to escape the suction chamber.
