摘要： A swash plate type compressor for use in an air-conditioning system for vehicles. The compressor has a pair of cylindrical cylinder blocks which are disposed in axial alignment and contact with each other, cylinder bores formed in the cylinder blocks and pistons reciprocatably received by respective cylinder bores. A rotary shaft extends through the cylinder blocks coaxially with the latter, and carries a swash plate fixed thereto. The pistons are slidingly engageable with the swash plate such that they make reciprocating movement in respective cylinder bores as the swash plate is rotated. The swash plate is accommodated by a crank chamber defined in the pair of cylinder blocks. A lubrication oil is supplied to the sliding parts in the crank chamber. A pair of side plates are attached to respective ends of the cylinder blocks which are axially disposed and contacted by each other, through medium of valve plates. The side plates cooperate with corresponding valve plates in defining therebetween suction chambers. The suction chambers are in direct communication with the crank chamber so that the blow-by gas within the crank chamber is sucked into the suction chambers. An oil chamber is provided at the bottom portion of the cylinder blocks and communicated with the crank chamber.

摘要： A vacuum actuator having a vacuum chamber and an atmospheric chamber separated from each other by means of a diaphragm, and an actuator rod connected at its one end to the diaphragm and extending across the atmospheric chamber to the outside of the actuator so as to be connected to an object to be actuated. An annular solenoid coil is mounted on the upper surface of the upper wall of the case defining the vacuum chamber, in such a manner that the axis of the solenoid coil extends substantially at a right angle to the axis of the actuator rod. A plunger disposed in the annular solenoid coil is adapted to be moved in one and the other directions along the axis of the annular solenoid coil. The end of the plunger is adapted to be moved into and out of a valve case in which is defined a control pressure chamber. A port for introducing a vacuum from a vacuum passage into the control pressure chamber and a port for introducing the atmospheric pressure into the same are formed in the valve case coaxially with each other. A valve member disposed between these ports is adapted to be displaced by the plunger so as to selectively open and close these ports. The pressurized fluid in the control pressure chamber is introduced into the vacuum chamber through a passage interconnecting the control pressure chamber and the vacuum chamber, thereby to produce a force which acts on the diaphragm.
