摘要： A variable delivery compressor containing a plurality of compression chambers and reciprocatory compression pistons is adapted for use in an air-conditioning circuit of a vehicle. The compressor has a suction chamber communicating with the compression chambers by way of a plurality of suction valves, some of which are capable of being deformed by a valve pressing mechanism from a first position, where the refrigerant is compressed, to a second position where the compression of the refrigerant is partially ineffective. The valve pressing mechanism contains an axially movable spool actuated by an actuating unit controlled by a cooling-load responsive control unit.

摘要： A variable-delivery refrigerant compressor wherein the delivery of a compressed refrigerant is adjustable by an actuator which is movable with a discharge pressure of the compressor between a first position at which plural discharge valves corresponding to compression chambers are rendered operative, and a second position at which at least one of the discharge valves is rendered inoperative. A pilot switch valve is disposed in a passage through which the discharge pressure is applied to the actuator. The switch valve controls a supply of refrigerant of the discharge pressure to the actuator such that the actuator is placed in the first position while a suction pressure of the compressor is relatively high, and in the second position while the suction pressure is relatively low.

摘要： The present invention contemplates a delivery control valve arrangement adapted for use in a refrigerant gas compressor of double-acting swash plate type in which its delivery capacity can be varied automatically by placing the compression chambers on one side of the compressor under "loaded" and "unloaded" conditions alternately in response to the cooling load. The valve arrangement includes valve means for establishing fluid communication passages for selective application of discharge and suction pressures of the compressor to a plunger movable between two positions corresponding to the loaded and unloaded conditions, respectively, and actuator means operable in response to evaporator-suction or suction-atmosphere pressure differential for actuating the above valves.

摘要： An image processor has a transparent plate on which a document is placed, and a document cover which covers the document placed thereon. The document cover moves freely between a closed position at which it covers the transparent plate and the document placed thereon and an open position at which it permits the transparent plate to be exposed. Provision is further made of a document illumination source which moves relative to the document placed on the transparent plate, and an image sensor which receives light irregularly reflected by the document that is illuminated by the document illumination source. The image processor further has a document detector which detects the region of the transparent plate where the document exists based on an output signal from the image sensor. The document covering surface of the document cover has a regular reflectance of from 1.5 to 40% and gives a relative intensity of irregularly reflected light as received by the image sensor of from N2.5 to N8.5 in terms of lightness in the Munsell color system. The document detector discriminates whether a document exists on the region of the transparent plate or not in a different manner depending upon whether the document cover is at the closed position or whether the document cover is at the open position.
