摘要： An arrangement of motor vehicle units includes a vacuum pump, a power brake unit, a pump which pumps a hydraulic fluid with a control pressure, and a control valve. The vacuum pump comprises a pump rotor, a coupling element, a control connection, a coupling arrangement switchable by the control connection to lock/unlock the coupling element with the pump rotor, and a suction connection. The power brake unit comprises a negative pressure chamber connected with the suction connection. The control valve, when unlocked, switches the control pressure of the hydraulic fluid through to the control connection to unlock. The control valve comprises an actuator acted on by a pressure of the negative pressure chamber which switches the control pressure through to the control connection if the pressure in the negative pressure chamber is greater than a threshold pressure so that the switchable control valve is switched into its unlocked state.

摘要： A positive displacement device includes a first cylinder, a second cylinder disposed within the first cylinder, and a third cylinder disposed around the first cylinder. An interior surface of the first cylinder and an exterior surface of the second cylinder define an inner cavity. An exterior surface of the first cylinder and an interior surface of the third cylinder define an outer cavity. A partition between the interior surface of the first cylinder and the exterior surface of the second cylinder divides the inner cavity into inner regions, and another partition between the exterior surface of the first cylinder and the interior surface of the third cylinder divides the outer cavity into outer regions. The second cylinder and the third cylinder orbit with respect to the first cylinder to create alternating regions of high pressure and low pressure in the inner regions and the outer regions.

摘要： A rotating vane vacuum pump includes a housing defining a cavity having an inlet and an outlet, a drivable vane member for a rotary driven movement inside the cavity, a rotor inside the cavity, and a rotatable central shaft extending into the cavity. The vane member is coupled to the central shaft by an eccentric element on the central shaft and movably arranged in the rotor, the rotor being rotatable together with said vane member upon rotation of the vane member. A rotational axis of the central shaft is offset from a rotational axis of the rotor and a point of action of the vane member is offset from the rotational axis of the central shaft by the eccentric element on the central shaft. The rotor encloses radially the eccentric element of the central shaft.

摘要： A negative pressure pump includes an electrically insulative casing an electrically conductive rotary shaft and an electrically conductive vane. The casing is formed in a tubular shape, an axial direction one end of which is closed off by a cap body. The rotary shaft is disposed in the casing, is mechanically and electrically connected to an earthed power source, and is rotated by power being transmitted from the power source. The vane is disposed in the casing, is supported at the rotary shaft to freely reciprocate in a direction orthogonal to the rotary shaft, and is electrically connected to the power source via the rotary shaft. The vane rotates integrally with the rotary shaft, and end portions of the vane slide over an inner wall face of the casing. The vane divides the interior of the casing into a plurality of spaces and generates negative pressure.

摘要： In a gas compressor, an outline shape of an inner peripheral surface (41) of a cylinder (40) is set such that in a point before a first compression chamber (43B) adjacent to a second compression chamber (43A) in an upstream side in a rotational direction (W) is exposed to a discharge hole (45b) of a primary discharge portion (45) with rotation of a rotor (50) in the rotational direction (W) (point where the first compression chamber (43B) is positioned upstream of an angular position of being exposed to the discharge hole (45b) of the primary discharge portion (45)), a pressure of refrigerant gas (G) inside the compression chamber (43) reaches a discharge pressure. Therefore, the discharge hole (45b) of the primary discharge portion (45) always discharges the refrigerant gas (G) from the compression chamber (43).

摘要： A pump that includes a pump body 10 which sucks in air from an inlet 7 and discharges the air; a hydraulic pump which pressure-feeds a lubricating oil to the pump body 10 in accordance with the driving of the pump body 10; a non-return valve 70 which is disposed in a valve accommodation portion 6 between the inlet 7 and the pump body 10 to open and close the valve accommodation portion 6; an air introduction path 19 which introduces air into a cylinder 74 of the non-return valve 70; and an air introduction valve 60 which opens the air introduction path 19 when the hydraulic pump is not operating. When the pump body 10 is stopped, the non-return valve 70 closes the inlet 7 in response to a difference in pressure between the pressure of the valve accommodation portion 6 reduced to a value equal to or less than atmospheric pressure by the operation of the pump body 10, and the pressure of the air introduced into the cylinder 74 by the opening of the air introduction valve 60 owing to the stoppage of the hydraulic pump associated with the stoppage of the pump body 10.

摘要： To allow a bush to stably rotate about a bush center, an end of a vane portion that is close to an inner circumferential surface center is always positioned on the inner side with respect to the bush center. Thereby, in a vane compressor a vane is stably supported, wear at a tip of the vane is suppressed, loss due to sliding on bearings is reduced by supporting a rotating shaft portion with a small diameter, and accuracy in outside diameter and center of rotation of a rotor portion is increased.
