    摘要: A cross section of a tooth profile of a first screw rotor (17) perpendicular to the rotor axis includes a tooth top arc (A1B1), a tooth bottom arc (C1D1), a first curve (A1C1), and a second curve (B1D1). The first curve (A1C1) is a first trochoidal curve that connects a first end (A1) of the tooth top arc (A1B1) to a second end (C1) of the tooth bottom arc (C1D1). The second curve (B1D1) connects the second end (B1) of the tooth top arc (A1B1) to the first end (D1) of the tooth bottom arc (C1D1). The second curve (B1D1) is a composite curve formed by an involute curve (B1E1) and a second trochoidal curve (E1D1), which extend continuously from each other at a first intersection point (E1). A screw pump (11) thus suppresses leakage of fluid with improved performance.

    摘要: A vacuum pump includes rotary shafts connected to a pair of screw-type rotors, respectively, and a pair of shaft retainers extending in the housing. Each shaft retainer supports the corresponding rotary shaft by means of a proximal bearing portion and a distal bearing portion. Each pair of the proximal and distal bearing portions are fixed in the axial direction with respect to the corresponding rotary shaft and shaft retainer. Lubricant oil is stored in an oil storage space in a gear case attached to the housing. A cooling water passage through which cooling water to cool the lubricant oil passes is formed in the gear case. A solenoid valve controls the flow rate of cooling water in the cooling water passage. A temperature sensor is provided in the oil storage space and detects the temperature of the lubricant oil. A controller controls the solenoid valve in accordance with the temperature detected by the temperature sensor, so that the temperature of the lubricant oil in the oil storage space is kept constant. With this configuration, when the bearing portions are fixed in the axial direction with respect to the rotary shafts and the shaft retainers, it is possible to prevent load from being applied to the bearing portions in the axial direction.

    摘要: A variable displacement swash-plate compressor includes a housing in which a suction chamber, a discharge chamber, a swash plate chamber, and a cylinder bore are formed, a drive shaft rotationally supported by the housing, a swash plate that is located in the swash plate chamber and rotated by rotation of the drive shaft, an actuator that changes the inclination angle of the swash plate, and a control mechanism that controls the actuator. A pressure regulation chamber is formed in the housing. The actuator includes a fixed body, a movable body that changes the inclination angle of the swash plate, and a control pressure chamber that moves the movable body. The control mechanism includes a control passage that connects together the discharge chamber, the pressure regulation chamber, and the control pressure chamber, and a control valve that, by adjusting the degree of opening of the control passage, changes the pressure in the control pressure chamber to allow the movable body to move. Refrigerant in the discharge chamber flows into the control pressure chamber via the pressure regulation chamber. The pressure regulation chamber functions as a muffler that reduces the pulsation of the refrigerant.

    摘要: A variable displacement swash-plate compressor includes an actuator that is configured to change the inclination angle of a swash plate. The actuator includes a movable body that moves along a drive shaft axis. The movable body includes an acting portion that is configured to push the swash plate with the pressure in a control pressure chamber. The swash plate includes a receiving portion that contacts and is pushed by the acting portion. The acting portion and the receiving portion contact each other at an acting position. A drive-shaft-parallel line segment is defined that contains the acting position and connects a proximal end of the acting portion and a proximal end of the receiving portion to each other, while extending in parallel with the drive shaft axis. The drive-shaft-parallel line segment is shorter when the inclination angle of the swash plate is maximized than when the inclination angle is minimized.

    摘要: A variable displacement swash-plate compressor includes an actuator (13) that is configured to change the inclination angle of a swash plate (5). The actuator (13) includes a movable body (13a) that moves along a drive shaft axis (O). The movable body (13a) includes an acting portion (14a) that is configured to push the swash plate (5) with the pressure in a control pressure chamber (13b). The swash plate (5) includes a receiving portion (5g) that contacts and is pushed by the acting portion (14a). The acting portion (14a) and the receiving portion (5g) contact each other at an acting position (F1). A bottom dead center associated part (U) for positioning the piston (9) at a bottom dead center is defined on the swash plate (5). When the inclination angle is minimized, the acting position (F1) is located at a position closer to the bottom dead center associated part (U) than the drive shaft axis (O).
