摘要： A rotor comprises a central body configured to rotate. A lobe extends perpendicularly from the central body along an lobe axis. A curved leading periphery and a curved trailing periphery are on opposite sides of the lobe axis. A V-shaped rib spans between the curved leading periphery and the curved trailing periphery. A first hollow space is bounded by the V-shaped rib, the curved leading periphery, and the curved trailing periphery. The first hollow space is distal with respect to the central body along the lobe axis. A second hollow space is bounded by the V-shaped rib, the central body, the curved leading periphery, and the curved trailing periphery. The second hollow space is proximal with respect to the central body along the lobe axis. The rotor can comprise a plurality of stacked, stamped sheets to form a helically twisted supercharger rotor.

摘要： A vacuum pump system for evacuating a chamber, in particular a lock or a process chamber, comprises a main vacuum pump preferably configured as a screw pump. An inlet of the main vacuum pump is connected with the chamber to be evacuated. As seen in the feeding direction of the main vacuum pump an auxiliary vacuum pump is arranged which is in particular a Roots pump. An outlet area of the main vacuum pump is connected with a main outlet on the one hand and an inlet of the auxiliary vacuum pump on the other hand. Further, an outlet of the auxiliary vacuum pump is connected with the main outlet.

摘要： A supercharger for a vehicle includes a lower body housing a compressor and an upper lid having a contraction chamber. The upper lid includes an air circulation port and is configured to be coupled to the lower body thereby forming a plenum. The contraction chamber is integrally formed in the upper lid adjacent to the air circulation port and includes an attenuator plate that defines a tuning neck. The tuning neck defines an inlet to and part of a volume of the contraction chamber, and includes a predetermined size and shape configured to attenuate a desired sound frequency generated by operation of the supercharger.

摘要： A supercharger transmission includes a first chamber having timing gears operatively disposed therein. A second chamber has transmission gears operatively disposed therein. An oil fill level is defined in the second chamber. A bearing retention wall is disposed between the first chamber and the second chamber. The bearing retention wall includes a return port to allow fluid communication between the first chamber and the second chamber. The return port is an aperture defined in the bearing retention wall below the oil fill level. The bearing retention wall also includes a crosstalk port to allow fluid communication between the first chamber and the second chamber. The crosstalk port is an aperture defined in the bearing retention wall above the oil fill level.

摘要： A supercharger includes a supercharger housing, a primary rotor having a primary rotor shaft fixed to rotate therewith. A ring gear with internal teeth is attached to a transmission housing portion of the supercharger housing. A sun gear is fixed to the primary rotor shaft. A planetary gear carrier has a plurality of planetary gear shafts. A plurality of planetary gears rotate about corresponding planetary gear shafts and are meshingly engaged with the sun gear and the ring gear and are substantially equally spaced about the sun gear. A rotatable input shaft is connectable to the planetary gear carrier. The input shaft is connectable to receive rotational motion and power from an engine.

摘要： A supercharger is provided that includes a housing having a first end and a second end. The housing may at least partially define a chamber and may include at least one rotor disposed within the chamber. The supercharger includes an inlet port proximate the first end of the housing and an outlet port proximate the second end of the housing. The supercharger further includes a relief chamber in fluid communication with the chamber. In an embodiment, the relief chamber may extend in the axial direction and may have a depth in the axial direction that is equal to at least about 10% of the axial length of the rotor.

摘要： A pumping system for evacuating an enclosure comprises a pumping mechanism (30), a motor (32) for driving the pumping mechanism, and a controller (36) for controlling the motor. The controller sets a maximum value for a rotational frequency of the motor and a maximum value for a current in the motor, and, to optimise the performance of the pumping system, independently adjusts the maximum values during evacuation of the enclosure.
