摘要： PURPOSE:To improve the controllability for the tilt angle of a swash plate and the center of revolution by selecting the pressure supplied into each control pressure chamber formed on the both surface sides of a piston by switching a control valve and driving a spool in the axial direction by the piston. CONSTITUTION:When a shaft 1 revolves, a swash plate 10 revolves around a spherical supporting part 405. Then, a piston 7 performs reciprocating movement in a cylinder 64 through each shoe 18, 19 by the swing movement of the swash plate 10. Therefore, the capacity in a compression chamber 50 is increased/decreased, and after gas coolant is inhaled into the compression chamber 50 from a suction chamber 72, said gas coolant is discharged into a discharge chamber 90. In this case, a control valve 400 is switched by a controller 500, and the pressure in the first discharge chamber 93 is introduced into the first control pressure chamber, and the pressure in a suction chamber 74 is introduced into the second control pressure chamber 122, and a piston 30 is shifted rightward. Therefore, the swash plate 10 is shifted rightward through a spool 40, and the stroke in the reciprocating movement of the piston 7 is reduced by reducing the swing quantity of the swash plate 10.

摘要： PURPOSE:To make it possible to change the position of the rotating center of a swash plate, by allowing a pin on the swash plate to be displaced in an elongated groove in a shaft in order to axially displace a variable member engaged with the swish plate so as to variably control the inclined angle of the swash plate. CONSTITUTION:A pin piercing hole 132 is formed in the power transmitting part 131 of a swash plate 130, and a pin 122 is disposed together with an engaging groove 121 so that a piston 108 is reciprocated by means of a shoe 124 on the swash plate 130. The pin 122 is reciprocated in the engaging groove 121 in association with the displacement of the swash plate 130 whose inclined angle is changed in accordance with the displacement of the piston 140. The axial displacement of a variable piston 141 is limited by stoppers 148, 149, and the position of the rotating center of the swash plate may be variably controlled.

摘要： PURPOSE:To reduce the consumption power of a pump by varying the discharge amount of the pump by selecting the number of operating chambers of the vane pump and the spool valves used. CONSTITUTION:The captioned vane pump has a noncircular cam ring 2, and has three operation chambers 18a, 18b, and 18c inside. Though into the operating chamber 18a, a suction passage 34 and a discharge passage 35 directly communicate, the communication to other operating chambers is performed through spool switching valves 30 and 32. Each spool switching valve is installed at one edge of a spool so as to shift by receiving the pilot pressure from the discharge passage, and when the discharge pressure increases, the operating chambers 18b and 18c are shurt-off from the suction and discharge passages, and the suction side and the discharge side of the operating chamber are short-circuited.

CONSTITUTION:A movable ring member 11 consists of a ring part 11 and a side plate 12 and is provided with a groove 14 in which a partition plate 18 is housed inside. Thickness of the partition plate 18 is equal to that of the side plate 12 of the movable ring member 1 and at one side of the partition plate, there is provided with a projection 18a which is fitted in a guide groove 81, guiding the partition plate. This partition plate 18 performs a horizontal motion alone so as to follow up the revolution motion of the movable ring member 1, and contacts a fixed ring member 9 all the time and that partitions the space into the suction side and the discharge side in a pump housing.

摘要： PURPOSE:To raise the pump efficiency, by making the configuration of the volute of a fixed scroll member and a movable scroll member which is turned around the fixed scroll member while keeping contact therewith by connecting a curve having smaller radius of curvature smoothly with a curve having larger radius of curvature successively. CONSTITUTION:A scroll pump of this invention comprises a fixed scroll member 1 and a movable scroll member 2. These two scroll members 1, 2 are both shaped in a volute form and held in contact with each other, and an enclosed space 30 is formed between them. Here, the configuration of the volute of these two scroll members 1, 2 is obtained by connecting a curve having a smaller radius of curvature smoothly with a curve having a larger radius of curvature successively. That is, a basic triangle A, B, C is at first drawn and small arcs (a), (b) are drawn at the vertices of the triangle. Then, the arcs (a), (b) are connected by a large arc (e). After the configuration of the fixed scroll member 1 is thus drawn, the confugration of the movable scroll member 2 is drawn at the position spaced from the fixed scroll member 1 a distance rho of eccentricity in the direction of its normal line. With such an arrangement, it is enabled to raise the pump efficiency and to reduce noise and vibration of the pump.

摘要： PURPOSE:To suppress the delivery pressure pulse by lagging the delivery opening position of the delivery stroke due to the cam curve by proper angle while pre- cmpressing the operation chamber prior to opening toward the delivery port. CONSTITUTION:When brought to section (b) of the cam curve due to the rotation of a cylindrical rotor 1, it will perform the inner compression because it is not opened toward the delivery port 8. Consequently the pressure in said operation chamber will increase and when the operation chamber in conducted with the delivery port 8, the pressure in the operation chamber can be brought higher than the oil pressure in the delivery port 8 continuously. As a result, the high pressure oil will not counterflow from the delivery port 8 side thus to suppress the delivery pulse caused by the counterflow of the high pressure oil.

摘要： PURPOSE:To prevent collision of the tops of a slide unit to the inner surface of a housing and to thereby ensure smooth rotation of the slide unit, by employing an arrangement in which guide members are fixed to a slide-unit guide shaft so that the slide unit can be slided by the aid of the slide members straightly in a direction perpendicular to the plane of the slide unit. CONSTITUTION:A slide unit 1 is composed by coupling two members 1b, 1c together by bolts 5 by the intermediary of a spacer 4, and the inner parts of the members 1b, 1c are supported on a slide-unit guide shaft 2 by the intermediary of slide members 3. The guide shaft 2 is disposed at a position displaced from the center of a rotor 6 toward the center of a housing 8 by a distance equal to that of eccentricity of the rotor 6 to the housing 8, in the manner that it can be rotated freely. Further, guide members 21 are fixed to the guide shaft 2 and slide members 3 are fitted in freely slidable manner in grooves 22 formed in the guide members 21, respectively. Therefore, when the rotor 6 is turned by an engine of an automobile or the like, slide unit 1 is rotated while causing relative sliding movement to the rotor 6 in its diametrical direction, with said sliding movement of the slide unit 1 being restricted by slits 61, 62 of the rotor 6 and grooves 22 of the guide shaft 2.
