摘要： A compressor having a shell formed by mutually coupling shell constitution members that are a closed-bottomed container-like housing and a front housing into which a drive shaft is inserted, a compression chamber forming body provided in the shell, and a coupling element for coupling and fixing the compression chamber forming body and the shell constitution member to each other. The coupling element is extended only in the region where the shell is present, and a hole in which the coupling element extends and that is formed in the shell constitution member to which the coupling element is coupled does not penetrate the shell constitution member but terminates in the wall of the shell constitution member. In the compressor, sealing ability for leakage of refrigerant can be remarkably enhanced and restrictions on external piping and apparatuses are relaxed to significantly increase the degree of design freedom.

摘要： A reciprocating compressor includes a discharge chamber, a suction chamber provided at a radially outer portion around the discharge chamber, and a reciprocating mechanism for compressing a gas introduced through the suction chamber. The compressor comprises a partition wall separating the suction chamber from the discharge chamber, and an outer wall extending along the suction chamber for defining the suction chamber. The outer wall has a plurality of portions projecting toward the partition wall on a radially inner surface of the outer wall, and arranged with an interval in a circumferential direction of the outer wall. Each projecting portion has an arc-projecting surface facing the partition wall, and an inclined surface facing the partition wall and extending from each side of the arc-projecting surface to the radially inner surface of the outer wall. Thus, a gas being compressed may be uniformly distributed from the suction chamber to the reciprocating mechanism.

摘要： A piston-type compressor has seven cylinder bores formed in a cylinder block which is formed in a compressor housing. A piston is slidably disposed within each of the cylinder bores. Each of the pistons includes a cylindrical main body and an engaging portion axially extending from the cylindrical body. A drive shaft is rotatably supported in the cylinder block. A bearing couples the plate to each of the pistons, so that the pistons reciprocate within the cylinder bores upon rotation of the plate which is tiltably connected to the drive shaft. A recessed portion is formed in an interior of the cylindrical body of each piston so that the cylindrical body forms a C-shaped cross-section perpendicular to longitudinal axis of the piston. Therefore, the configuration obtains lightweight pistons while simultaneously maintaining the efficiency of the compressor.

摘要： A piston-type fluid displacement apparatus includes several pistons, each of which is slidably disposed within one of several cylinder bores. A plating layer, which includes a self-lubricating material, is coated on a peripheral surface of each piston. At least one annular groove is formed on a periphery surface of each piston, and, at least one piston ring is disposed within the annular groove of each piston for sealing a gap between the piston and the cylinder bore. Thereby, the piston-type fluid displacement apparatus may be simply manufactured at a reduced assembly cost while simultaneously prolonging the life of the piston rings and while reducing or eliminating a decrease in compression efficiency during the operating life of the piston-type fluid displacement apparatus.

摘要： A piston-type fluid displacement apparatus includes a housing enclosing a crank chamber, a suction chamber, and a discharge chamber. Discharge conduits are formed at a top dead center position of the piston. A control device includes valve members having suction apertures and discharge apertures for opening and closing the suction conduits and the discharge conduits. The control device further includes a driving mechanism joined to the valve members for driving the valve members to gradually open each of the suction conduits during the suction stage of the piston and to gradually close each of the discharge conduits during the discharge stage of the piston. Thus, the piston-type fluid displacement apparatus may prevent the valve assembly from stopping or sticking at the sliding contact surfaces of the suction and discharge holes to allow the pistons to reciprocate smoothly within each cylinder without reducing the compression efficiency. Further, the piston-type fluid displacement apparatus also improves the sealing performance between the valve assembly and the sliding contact surfaces of the suction and discharge holes.

摘要： In a reciprocating compressor in which a suction chamber (7) extends around a discharge chamber (6) parallel to suction, a discharge gas conducting passage (6c) is connected to the discharge chamber and is adjacent to a suction gas inlet passage (7a) in a predetermined direction orthogonal to the plane. The suction gas inlet passage communicates with each of the first and second opposite ends of the suction chamber so that gas is supplied into the suction chamber through each of the first and second opposite ends thereof. A plurality of compression elements are arranged along the suction chamber and connected to the discharge chamber and the suction chamber. Each of the compression elements have a piston (16) which reciprocates to introduce the gas from the suction chamber, to compress the gas, and then to discharge the gas into the discharge chamber.
