摘要： The subject matter of this specification can be embodied in, among other things, a fluid pump that includes a housing with a cam block. The pump also includes a collection of vanes, each having a shank having a leading edge and a trailing edge, and a head having a curved outer side. The pump also includes a rotor having a collection of slots, each slot having substantially parallel leading and trailing edges spaced to accommodate the shank of one of the vanes, wherein each vane contacts the cam block at a contact point on the head controlled by the rotor slot position and the head outer curved surface, the contact point being located relative to the shank edge when the vane is radially aligned with the major and minor radii, and located rotationally to create a radial force between the head curved surface and the cam block.

摘要： A hydraulic screw machine including a drive screw and at least one running screw co-operating therewith are arranged inside a housing, the drive screw being united with a shaft extending out through the housing at the high pressure side of the machine and being provided with a balancing piston for balancing a part of the axial force acting on the drive screw and also with a collar which together with a wall portion of the housing forms a hydrostatic axial bearing for taking up the remaining axial force acting on the drive screw. The bearing surfaces of the axial bearing are kept separated by a spring means during starting and similar operating conditions. An axially limitedly movable rolling bearing is mounted in association with the hydrostatic axial bearing and takes up axial forces on the drive screw occurring in certain operating conditions.

摘要： A vane pump is disclosed that includes a plurality of vanes and radial slots configured to provide a gap between the vane and the radial slot such that the vane has a different angular position relative to the direction of rotation in a radially extended position compared to an angular position in a radially-retracted position. The different angular positions provide different orientation of the arcuate surface of the vane tip portion with respect to the cam body inner surface, thus providing different fluid stop points on the vane tip portion arcuate surface.

摘要： A Roots type blower is disclosed having rotors with twisted-shape and projections on the pitch circle. The blower is compact in the axial direction, because the projections work as gearing between the rotors. Therefor, it is not necessary to provide additional gears for driving the rotors. Each of the rotors has a twisted-shape with a relationship of n.times..theta..gtoreq.2.pi., where n is the number of leaves and .theta. is the lead angle.

摘要： A rotary fluid machine such as, for example, a screw compressor, a centrifugal compressor, or a pump, is provided with a thrust bearing mounting unit adapted to maintain natural frequencies of bending vibrations of rotors thereof within ranges of permissible values. The axial rigidity of the mounting unit is at least as high as that of the thrust bearings and the radial rigidity thereof is made to be not more than half that thereof. When a radial load is applied to the thrust bearings, the bearing mounting unit is deformed solely substantially in the radial direction and the thrust bearings bear substantially no radial load.
