摘要： In an electric motor, its motor frame has a shaft hole, a shaft is fitted in the shaft hole in such a manner that its one end potion is in the shaft hole while the other end portion is extended outside the motor frame. The motor frame includes a bearing-receiving portion extended therefrom in such a manner that the bearing-receiving portion confronts with the inner race of a rolling bearing fitted on the end portion of the shaft, and has a wall surface which merges with the wall surface of the shaft hole. The shaft has a groove which is covered by a part of the inner cylindrical surface of the inner race of the ball bearing and by the wall surface of the protruded portion. The inner raced is fixedly secured to the shaft with adhesive.

摘要： A rotary compressor has a plurality of vanes which are slidably disposed in radial slots of a rotor to define fluid chambers in cooperation with a cylindrical housing. The radially innermost end of each vane, rotor and opposite ends of the housing define a back-pressure chamber which is supplied with a pressure during a suction stroke for maintaining the associated vane in sealing contact with the inner wall of the housing. Each of opposite ends of the housing has a unique configuration which damps the pressure in the back-pressure chamber when the chamber is fluidly isolated from a source of the pressure supply during a compression stroke, thereby eliminating excessive friction between the vane and the housing.

摘要： A swash plate compressor is disclosed which is provided with a compression capacity control apparatus capable of returning an output pressure of a high pressure chamber of one cover to a low pressure chamber of the same cover. The control apparatus comprises a delivery chamber which is communicated with a high pressure chamber of the other cover, isolated from the high pressure chamber of the one cover and connected to a delivery conduit. The control apparatus also comprises a compression capacity control passageway providing communication between the delivery chamber and the low pressure and high pressure chambers of the one cover. A rotary three-way valve member is disposed in the control passageway to interrupt the communication between the delivery chamber and the high pressure chamber of the one cover while establishing communication between the low pressure and high pressure chambers of the one cover. A relief valve is provided to communicate to the delivery chamber an elevated pressure in the compression chamber of the one cover while the rotary valve member shifts from one position to another.

摘要： A portion of the endless camming surface of the pump housing, which performs one cycle of suction, compression, and discharge of fluid in cooperation with the vanes and the rotor, includes an increasing radius portion and first through fourth decreasing radius portions successively arranged in the advancing direction of the vanes. These camming surface portions have such cam profiles that with movement of each vane, the amount of protrusion of the vane gradually increases along the increasing radius portion, and gradually decreases along the decreasing radius portions, the receding speed of the vane gradually increasing along the first and third decreasing radius portions, and gradually decreasing along the second and fourth decreasing radius portions. The cam profiles may preferably vary along quadratic curves. Preferably, the above one cycle performing portion further includes one or two constant radius portions located between the above five portions, along which the amount of protrusion of each vane is kept substantially constant with movement of the vane.

摘要： A rotor is eccentrically journalled for rotation within a bore of a stationary housing formed with end walls and inlet and outlet ports. One or more blades are radially slidable within grooves in the rotor and biased into sealing engagement with the inner circumference of the housing. Rotation of the rotor and blades produces suction and pressure chambers within the housing to displace fluid from the inlet to the outlet. The rotor and blades are each formed in two sections with a resilient member inserted inbetween, the resilient members urging the respective sections longitudinally into sealing engagement with the end walls.

摘要： In a spindle motor 1, a motor frame 21 is molded from a resin. Therefore, even if an impact is applied to a motor apparatus in which this motor 1 is installed, the impact can be absorbed and hence moderated by the motor frame 21, and ball bearings held by the motor frame 21 can be prevented from being deformed. In addition, since lead terminals 4 for feeding an armature are insert molded in a bottom portion 213 of the motor frame 21, there is no need to use a connector that prevents the miniaturization of the motor or an FPC board which may cause a risk of a wiring pattern being disconnected.
