摘要： A pump device includes: a main pump and a sub pump; and a switching valve that switches so as to supply the hydraulic oil discharged from the sub pump to the hydraulic device, or to return the hydraulic oil discharged from the sub pump to the suction side. The main pump and the sub pump each include: a rotor, a discharge port into which the hydraulic oil discharged from a pump chamber is led, and a groove-shaped discharge-side notch formed from an opening edge of the discharge port toward a direction opposite to a rotation direction of the rotor. The switching valve switches according to a rotation speed of the drive shaft. At least one discharge-side notch of the sub pump is formed so that a resistance applied to the flow of the hydraulic oil passing therethrough is greater than that of the discharge-side notch of the main pump.

摘要： A scroll pump isolates vibrations of a pump head/motor assembly of the pump from the exterior of the pump and thus, suppresses the production of airborne noise. The pump includes a sound-muffling enclosure surrounding the pump head/motor assembly, feet supporting the enclosure, and elastic vibration isolators. The pump head/motor assembly is fixed to the tops of the vibration isolators, and the sound-muffling enclosure is fixed to the vibration isolators at the bottoms of the isolators. The scroll pump also has a locking system by which motion of the pump head/motor assembly relative to the sound-muffling enclosure can be limited or prevented, and by which the sound-muffling enclosure can be hard-mounted to a support surface independently of the feet.

摘要： A screw compressor utilizing radial and axial or thrust bearings to maintain the position of the rotors radially and axially and utilizing a damping fluid to dampen rotor vibrations. The damping fluid may conveniently be provided in the form of lubricant that is already used in the compressor to seal the clearances between the rotors and between the rotors and the cylinder during compression. The damping fluid is included in a squeeze film damper, arranged in a parallel arrangement with the radial or thrust bearings, which provides viscous damping to the rotor. The introduction of additional viscous damping such as may be provided by squeeze film dampers may result in significant reduction of compressor vibration regardless of the source of vibration.

摘要： With regard to a scroll compressor, a compression portion is rotatably connected with one end portion of a rotating shaft. A first shaft portion formed at one end portion of the rotating shaft is supported through a first bearing by a partition. A second shaft portion formed at the other end portion of the rotating shaft is supported through a second bearing by a cylindrical shaft support. A coil spring is interposed between a second inner race of a second bearing and a spring receiving portion of the rotating shaft which faces the second inner race in the shaft direction of the rotating shaft. The structure reduces vibration toward the shaft length direction of the rotating shaft and minimizes common vibrations together with vehicle side vibrations.
