摘要： An axial multi-piston compressor includes a drive shaft, a cylinder block having cylinder bores formed therein and surrounding the drive shaft, and a plurality of pistons slidably received in the respective cylinder bores, wherein the pistons are successively reciprocated in the cylinder bores by a rotation of the drive shaft so that a suction stroke and a discharge stroke are alternately executed in each of the cylinder bores. During the suction stroke, a fluid is introduced into the cylinder bore, and during the compression stroke, the introduced fluid is compressed and discharged from the cylinder bore such that a residual part of the compressed fluid is inevitably left in the cylinder bore when the compression stroke is finished. The compressor further includes a rotary valve for allowing the residual part of the compressed fluid to escape from the cylinder bore into another cylinder bore governed by the compression stroke.

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： An axial multi-piston type compressor includes: a drive shaft; a cylinder block having cylinder bores surrounding the shaft, a central circular space, and respective radial passages for communicating the bores with the space; pistons slidably received in the respective bores, and a housing associated with the block to define a crank chamber. The pistons are successively reciprocated in the bores by a rotation of the shaft so that a suction stroke and a discharge stroke are alternately executed in each bore. A suction rotary valve is rotationally and slidably received in the space to be cooperated with the passages for successively introducing a fluid into the bores subjected to the suction stroke, through the corresponding passages thereof, and for successively closing the passages of the bores subjected to the compression stroke. A leakage of a compressed fluid occurs at openings of the passages of the bores subjected to the compression stroke, and prevails in a clearance between an outer surface of the valve and an inner surface of the space. The valve includes a circular groove passage formed in the outer surface thereof for recovering the leakage to prevent introduction of the leakage into the crank chamber.

摘要： A swash plate type variable displacement compressor comprises cylinder bores, pistons, a suction chamber and a discharge chamber. A suction valve introduces a low pressure gas into a working chamber in each cylinder bore. A discharge valve introduces a high pressure gas in the working chamber into the discharge chamber during a compression stroke. A crank chamber communicates to each of the cylinder bores at rear sides of the pistons. A swash plate is tiltably supported on a drive shaft and connected to each of the pistons through associated rods. The swash plate makes the pistons reciprocate in response to its undulating swing motion and varies its inclination angle based upon pressure differential between pressure in the suction chamber and pressure in the crank chamber therefore adjusting discharge displacement. A gas supply passage communicates each cylinder bore to the crank chamber in order to supply gas having a lower pressure than that in the working chamber at the time of completing the compression stroke. A gas bleed passage communicates the crank chamber to the suction chamber in order to introduce gas in the crank chamber into the suction chamber. A pressure control valve is provided in the gas supply passage or the gas bleed passage to control pressure of gas in the crank chamber. A valve is provided for opening and closing the gas supply passage in the middle of the compression stroke of each of the pistons.

摘要： A compressor includes swash plate, which is tiltably supported by a drive shaft. The displacement of the compressor changes in accordance with the inclination angle of the swash plate. The minimum inclination angle (&thgr;min) of the swash plate is less than three to five degrees relative to a plane perpendicular to the axis of the drive shaft. The swash plate can be moved from its minimum inclination to increase its angle, despite the small minimum inclination angle, due to a return spring, which urges the swash plate to increase the inclination angle. The return spring positively moves the swash plate in a direction increasing the inclination angle.

摘要： A control valve is used in connection with a variable displacement compressor that varies the discharge capacity by controlling an inclination of a cam plate located in a crank chamber. The inclination of the cam plate is variable based on crank chamber pressure caused by refrigerant in the crank chamber. Monitor pressure is monitored at a predetermined point in a refrigerant circuit for causing a change in the crank chamber pressure and ultimately varying the discharge capacity. The control valve has a housing, an internal control valve mechanism and an external control valve mechanism. The internal control valve mechanism is located inside the valve housing and has a first valve body and a first reacting member. The first reacting member is connected to the first valve body for reacting to the monitor pressure to cause a change in the crank chamber pressure. The external control valve mechanism is located inside the valve housing and has a second valve body and a second reacting member. The second reacting member is for reacting to an external signal to cause the second valve body to change in the crank chamber pressure. The internal control valve mechanism and the external control valve mechanism operate independently with each other.

摘要： A swash plate is mounted on a drive shaft disposed in a housing having a gas suction chamber in such a way that the swash plate is rotatable integrally with the drive shaft. A plurality of cylinder bores are formed around the drive shaft, extending along the drive shaft. Disposed in each cylinder bore is a piston, which reciprocates between top and bottom dead centers by undulating movement of the swash plate caused by rotation of the drive shaft. A compression chamber where gas is compressed by the reciprocal movement of the piston is defined in each cylinder bore. Provided between the drive shaft and the swash plate is a mechanism for altering an angle of the swash plate with respect to the axis of the drive shaft to change a reciprocal stroke of the piston to thereby control compression displacement. A rotary valve is provided at the drive shaft to be rotatable integrally with the drive shaft. The rotary valve has a passage for permitting uncompressed gas to move to each compression chamber from the suction chamber in synchronism with the reciprocal movement of the piston during rotation of the rotary valve before the piston reaches the bottom dead center. The compressor further comprises a mechanism for forcibly changing the timing at which the piston substantially reaches the top dead center in accordance with an inclined angle of the swash plate.
