摘要： A variable displacement compressor has a sleeve axially slidably mounted on an axial drive shaft and a swash plate tiltably connected to the sleeve. The angle of the tilt of the swash plate is variable by an axial movement of the sleeve and a movement of the swash plate along a guiding cam track to vary the compressor displacement. The guiding cam track is provided by a cam groove having a form of a closed loop and formed in a driving plate drivingly connected to the drive shaft and to the swash plate to transmit the torque of the drive shaft to the swash plate. A fulcrum pin is provided on the swash plate and engaged in the cam groove and is movable along the guide groove toward the drive shaft as the angle of tilt of the swash plate is decreased.

摘要： A refrigeration system includes a variable-capacity compressor having a compression chamber for sucking and compressing a refrigerant and a crankcase surrounding a swash plate forming a drive portion for suction and compression, and a passage through which the refrigerant discharged from the outlet of the compression chamber passes at least through a condenser, an expansion means and an evaporator and is sucked into the inlet of the compression chamber of the compressor, the capacity of the compressor being changed by slanting the swash plate during its rotation. A pressure control device is provided in a refrigerant passage between the evaporator and the suction valve of the compressor whereby the pressure upstream thereof is controlled in such a manner that it does not decrease below a predetermined value, thereby preventing frosting of evaporator fins. A point partway along the passage upstream from the pressure control device and the crankcase of the variable-capacity compressor are communicated so that the capacity of the compressor may be controlled without controlling the pressure in the crankcase.

摘要： The variable capacity swash plate compressor of the present invention includes a rotary swash plate having an eccentric mass located opposite to the driving point of the swash plate with respect to the axis of the same. The mass distribution in the rotary swash plate is established such that, within a range in which the piston stroke is less than a predetermined value, a moment about a pivot point produced by the rotation of the swash plate becomes larger than a moment produced by the reciprocating motion of pistons, piston rods and the like and acting upon the swash plate, while, within a range in which the stroke is larger than the predetermined value, the former moment becomes smaller than the latter moment. Accordingly, it is possible to provide a compressor of the type in which its capacity control characteristics are improved over a wide shaft speed range.

摘要： A variable displacement swash plate type compressor is suitable for use as a refrigerant compressor for automobile air conditioner. The compressor includes pistons, an oscillating member for driving the piston, a rotating member for oscillating the oscillating member, a plate member for imparting a rotational force to the rotating member, and a main shaft connected to the plate member. A member, having a spherical or cylindrical surface portion and a flat surface portion, is provided between the rotating member and the plate member in such a manner that it is slidably in contact with both of the rotating member and the plate member. Also, movement of the oscillating member is defined by contact of the oscillating member with a stationary member. Consequently, it is possible to provide a variable displacement swash plate type compressor which assures reliable capacity control at a high-speed rotation and which vibrates and wears less. Furthermore, it is possible to prevent application of a thrust load to the drive shaft.

摘要： A fuel supply system for a direct injection engine which has a variable capacity single cylinder plunger pump and two fuel rails. Offices are disposed at the upstream side inlets of both fuel rails, respectively. At the opposite sides to the inlet sides, the fuel rails are interconnected with each other by a connecting pipe. Using this fuel supply system, it is possible to increase a characterisitic frquency of the fuel columns, and to stabilize, suppress, and smooth out pressure pulsation in the fuel rails, thereby reducing uneven fuel injections into the cylinders. The system may have a cam which drives a plunger of a high pressure fuel pump to reciprocate once for every two combustions in two engine cylinders.
