Abstract: 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 concerned, and during the compression stroke, the introduced fluid is compressed and discharged from the cylinder bore concerned, such that a residual part of the compressed fluid is inevitably left in the cylinder bore concerned 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 concerned into two other cylinder bores disposed adjacent to each other and subjected to the compression stroke.

Abstract: 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.

Abstract: Shoes for operatively connecting a swash-plate with the compression pistons of a swash-plate type compressor are made from a novel Cu-based alloy. Improved shoes are characterized by a combination of high heat conductivity and excellent wear resistance properties particularly when subjected to a lubricating condition so severe that no lubricating oil is supplied to the surface of the shoes at the initial period of the compressor operation. Phosphorus and elements of C group (Pb and/or Sn), as well as elements of A group (Mn and Si) and/or B group (the IVb and VIb groups of the periodic table), are added in predetermined amounts to the Cu-based alloy, so that the properties mentioned above are simultaneously obtained. The compressor according to the present invention can be reliably employed, without the occurrence of seizure over a long operational period for air-conditioning vehicles, in which the sliding condition of the shoes is drastically varied with the rotation of the engine.

Abstract: A variable displacement hydraulic system contains a housing, a cylinder block provided with a plurality of pistons movable in reciprocation, and a swash plate for controlling reciprocation of each of the pistons so that the swash plate is slantwise rotatable along a slidable contact surface of arcuate shape. A thrust metal is mounted to an arcuate contact surface of the housing. Arcuate plates having smooth surfaces of high sliding efficiency are fixed onto outwardly curved portions formed at the rear surface of the swash plate, which is in contact with the thrust metal. Alternatively, a smooth surface layer having a high sliding efficiency is formed on the swash plate by applying chemical processes, thereby reducing the sliding resistance of the swash plate and improving the ease with which the swash plate is restored to the neutral position.

Abstract: A compressor comprises a cylinder block having cylinder bores formed radially spaced from and circumferentially distributed equidistantly about the cylinder longitudinal axis. Pistons are slidably received in the respective bores for reciprocation therein executing alternately suction and discharge strokes. The compressor also has a discharge valve assembly for controlling discharge of a compressed fluid from each of the bores into a discharge chamber, which assembly is axially movable between a first position in which the assembly is abutted against an end wall of the block and a second position in which the assembly is spaced from the end wall of the block to define a narrow space therebetween to interconnect the bores with each other. When the assembly is pushed toward the second position by the pressure of the compressed fluid during initial running of the compressor, bypass channels interconnect the cylinder with the discharge chamber.

Abstract: A slant plate type compressor with a capacity or displacement adjusting mechanism is disclosed. The compressor includes a housing having a cylinder block provided with a plurality of cylinders and a crank chamber. A piston is slidably fitted within each of the cylinders and is reciprocated by a drive mechanism which includes a member having a surface with an adjustable incline angle. The incline angle is controlled by the pressure in the crank chamber. The pressure in crank chamber is controlled by control mechanism which comprises a passageway communicating between the crank chamber and a suction chamber, a first valve device to control the closing and opening of the passageway and a second valve device to control pressure in an actuating chamber. The first valve device includes a bellows valve element and a valve shifting element. The valve shifting element of which one end is exposed in the actuating chamber is coupled to the bellows to apply a force to the bellows at another end and thereby shift a control point of the bellows in response changes in the actuating chamber pressure.
