摘要： The oscillating plate compressor includes a box housing a rod (30) chamber, with cylinder bores (28) and pistons (29) arranged in the bores. An oscillating plate (35) is driven by a drive shaft (25). Each piston has at its end an end piece (41) consisting of two parts (41a,41b) placed on either side of the axis, and a third part (41e) extending the axis and linking together the first and second parts. Articulated skates are arranged between the oscillating plate (35) and the first and second parts of the end piece (41a,41b) to convert the rotary movement of the oscillating plate (35) into an alternating movement for the piston (29). A greasing hole (50) is formed in the second part of the end piece (41b) for the passage of fluid into the container of the second part of the end piece on the side which is distant from the cylindrical bore (28) and the rod chamber (30).

摘要： PCT No. PCT/JP94/00026 Sec. 371 Date Aug. 31, 1994 Sec. 102(e) Date Aug. 31, 1994 PCT Filed Jan. 11, 1994 PCT Pub. No. WO94/16225 PCT Pub. Date Jul. 21, 1994A control valve for a variable displacement refrigerating compressor for an automobile climate control system for controlling fluid communication between the crank chamber and the discharge chamber of the compressor. The valve has axially arranged pressure-sensing unit having a diaphragm (13), a valve unit (17,23c) arranged so as to control a fluid communication of the passageway (23a) between the crank and discharge chambers of the compressor, a compensating unit having a balancing rod (18) compensating for the fluid-communication controlling operation of the valve unit (17,23c) in relation to the crank-pressure (Pc) and the discharge pressure (Pd), and a compensation-stopping unit (19,25) stopping the compensation operation of the compensating unit. The control valve permits the compressor to exhibit a satisfactory refrigerating performance irrespective of the ambient temperature.

摘要： The swashplate multi-piston refrigerant compressor is for the air conditioning system of a vehicle. Actuation devices are provided with whose help the suction valves are mechanically movable relative to the suction openings (30b) from their closed position to an open position in a sequence in synchronisation with the piston strokes (42). The suction valves have a plate-shaped rotatable valve element with a curved elongated hole serving as a suction channel and arranged in the suction chamber of the housing. USE/ADVANTAGE - Vehicle air-conditioner compressor in which refrigerant pressure losses are reduced and noise generation at the valves is avoided.

摘要： The cylinder block (1) contains numerous bores (32) for bolts (5) securing a front and rear housing (2) to the cylinder block with a cylinder bore (9). In the block are formed a crank (17), a suction (11), and a delivery chamber (13), with the crank chamber retaining a drive plate (25) on a drive shaft (6). The pressure passage is partly formed in one bolt retaining bore and connects the crank and suction chambers. Thus a large demand on pressure in the crank chamber can be taken and this is compressed by the piston (10) in the cylinder bore. This then leaks from the bore into the crank chamber.

摘要： A variable capacity swash-plate type compressor provided with a suction chamber for refrigerant gas before compression, a discharge chamber for compressed refrigerant gas, a crank chamber for a swash-plate assembly driving reciprocation of compressing pistons in cylinder bores of a cylinder block, a high pressure gas supply passageway fluidly communicating between the discharge chamber and the crank chamber so as to supply the crank chamber with a high pressure gas, a flow choke arranged adjacent to the high pressure gas supply passageway so as to regulate the pressure and flow rate of the high pressure gas flowing through the gas supply passageway, and a control valve unit for controlling extraction of the high pressure gas from the crank chamber toward the suction chamber in response to a refrigerating load. The high pressure gas supply passageway is formed in the cylinder block, and the flow choke is provided in a discharge valve assembly including a valve plate, a discharge valve element, and a valve retainer.

摘要： PROBLEM TO BE SOLVED: To combine vehicle acceleration and air-conditioning action by maintaining air-conditioning action even during vehicle acceleration without impairing accelerating performance of a vehicle in an air conditioner for the vehicle. SOLUTION: An air conditioner for a vehicle is provided with a variable displacement compressor using a vehicle engine as a drive source and provided with a variable set pressure type capacity control valve 50; a vehicle speed sensor 87; a sensor 88 for detecting accelerator opening; and an A/C controller 80 controlling current application to the control valve on the basis of various external information. The controller 80 computes to update the judgment value of accelerator opening on the basis of information from the vehicle speed sensor 87, and changes the set pressure of the control valve 50 to reduce the discharge capacity of the compressor when the accelerator opening detected by the sensor 88 is the judgment value or more.

摘要： PROBLEM TO BE SOLVED: To improve contact sliding property between members, and increase a delivery capacity by forming a solid lubricating film on a sliding surface of one side member which is brought into mutually contact freely to relatively slide, forming a soft film on a sliding surface of the other member, and forming a solid lubricating component as a solid lubricating component other than soft metal. SOLUTION: A recessed part for advancing an outer peripheral part of a swash plate 10 and a pair of shoes 20A, 20B is formed on an end part of a piston 8. A projection spherical surface 21 as a sliding surface is formed on both shoes 20A, 20B. A recessed spherical surface 81 as a sliding surface which is brought into opposing contact with the projection spherical surface 21 is formed on the recessed part of the piston 8. The piston 8 and a swash plate 10 are made of aluminum alloy, and both shoes 20A, 20B are made of a bearing steel as an iron system material. Each of films 22, 82 are formed on the projection spherical surface 21 and the recessed spherical surface 81. A solid lubricating film including molybdenum disulfide is formed as the film 22, and a soft film serving tin as a principal is formed as the film 82.
