摘要： In a swash-plate compressor, pistons are slidably received in cylinder bores. A drive shaft is extended through a crank chamber, and is rotated through an electromagnetic clutch means associated therewith. A conversion mechanism is provided on the shaft for converting a rotational movement of the shaft into a reciprocation of each piston in the corresponding cylinder bore such that a suction stroke and a discharge stroke are alternately executed therein. A fluid is introduced from a suction chamber into the bore during the suction stroke, and during the compression stroke, the fluid is compressed in and discharged from the bore into a discharge chamber. The conversion mechanism is constituted such that a stroke length is shortened in response to an increase of a pressure in the crank chamber, and vice versa. A first passage communicates the crank with the suction chamber, and a second passage communicates the crank chamber with the discharge chamber. A control valve is provided in one of the first or second passage, and is magnetically actuated by the clutch for controlling the pressure in the crank chamber such that the piston stroke can be minimized whenever the clutch is electrically deenergized.

摘要： To the front end face of the compressor cylinder block (1) is secured a front housing (2), while a rear one (4) is fastened to the rear end face. The fastening uses valve plates (3) and a seal (29) to define a crank chamber (17), a suction chamber (11), and a delivery chamber (13), with the crank chamber retaining a drive plate (20) on a drive shaft (6). The drive shaft rotation is converted by the plate into a reciprocal motion of a piston (10) in the cylinder bore (9). The chambers are interconnected by a pressure passage, also controlling the crank chamber pressure. The passage is defined partly by an indentation, contg. the seal, and is narrower than the rest of the passage for pressure control.

摘要： A variable capacity type swash plate compressor includes a novel hinge means. The hinge means includes a supporter arm, a main guide pin, and an auxiliary guide pin. The supporter arm is disposed on the rotor projectably therefrom toward the swinging swash plate, and has a main guide hole extending perpendicularly with the driving shaft. The main guide pin is inserted rotatably into the main guide hole. The auxiliary guide pin is inserted slidably into a hole, formed in one of the main guide pin and the swinging swash plate, perpendicularly with the main guide pin at one end, and it is fixed to another one of the main guide pin and the swinging swash plate at the other end. With the hinge means, the top clearances of the pistons can be always maintained virtually uniformly, and the moments resulting from the compression reactive forces can be inhibited from interfering with the discharge capacity control. Additionally, the compressor can attain the reduction in the manufacturing costs.

摘要： PURPOSE:To heighten the controllability of discharge capacity and reduce the shell diameter of a compresor by forming a hinge mechanism of support arms and guide pins inserted slidably into guide holes, and inclining the hinge mechanism in such a way as to follow a circular arc described passing grip parts from the axis of a driving shaft. CONSTITUTION:A pair of hinge mechanism K, K are provided with support arms 18A, 18B provided in the backward protruding state at a rotating support body 10, and guide pins 21A, 21B are slidably inserted into guide holes provided at the grip parts 18a, 18b of the support arms 18A, 18B. The grip parts 18a, 18b are provided in such a way as to be laterally symmetrical with the top dead center position T of a cam plate 14 held in between, and these grip parts 18a, 18b forming an approximate rectangle within the axial plane of projection are inclined in such a way as to follow an circular arc described passing the grip parts 18a, 18b from the axis of a driving shaft 6. The cam plate 14 can be thereby tilted smoothly in both directions of increasing/decreasing the tile angle.

摘要： The compressor has a cylinder head (20) which is fastened to the rear end of a cylinder-block arrangement of a compressor with a valve plate (5) inserted in between and which has a suction chamber (9) formed in it, which is formed in its radially outer area so that it surrounds a central outlet chamber (8). A cooling-gas inlet passage (21) is provided there in the compressor. The cooling-gas inlet passage (21) extends radially straight through the axial centre of the compressor and has at least two bores (23, 23) for creating a direct connection between the gas inlet passage (21) and the suction chamber (9) at two positions which are at a radial distance from one another. The cooling-gas inlet passage (21) can have a combination of at least two passage sections (21a, 21b) with different cross-sectional areas.
