摘要： An interior permanent magnet motor includes a rotor and a stator. The rotor includes a rotor core. The rotor core is formed by laminating steel plates each including pairs of magnet insertion holes and pairs of cutouts. Each pair of magnet insertion holes includes two magnet insertion holes that are arranged in a V-shape, the wide end of which is relatively closer to the outer edge with a support portion located in between. Each pair of cutouts is formed at q-axis ends of the corresponding magnet insertion holes, and includes two cutouts connected to the outer edge of the rotor core. In a state where the permanent magnets are inserted in the magnet insertion holes, a gap is formed at a d-axis end of each magnet insertion hole.

摘要： An accommodating recess (21A, 21B) has a magnet accommodating portion (19A, 19B) for accommodating a permanent magnet (17A, 17B) and a cavity (20A, 20B), which is located at the q-axis side of the magnet accommodating portion. The cavity opens through a rotor outer circumferential surface (162). A starting point (Pa1, Pb1) of an outer cavity forming surface (201A, 201B) is located on the rotor outer circumferential surface. The outer cavity forming surface intersects either a magnetic pole surface or an imaginary extended plane (23A, 23B) of a magnetic pole facing surface (191A, 191B). The rotor outer circumferential surface (162) includes portions of an imaginary annular line (E). A starting point (Pa1, Pb1) of the outer cavity forming surface (201A, 201B) is located between the d-axis and an intersection point (Qa, Qb) between the imaginary annular line and the imaginary extended plan of the magnetic pole facing surface.

摘要： An electric pump for supplying a hydrogen gas to a fuel cell includes a rotary shaft rotatably inserted through an electric motor, a transmitting member provided on one of an outer peripheral surface of the rotary shaft and an inner peripheral surface of the electric motor so as to be rotatable therewith, and a groove formed in the other of the outer peripheral surface of the rotary shaft and the inner peripheral surface of the electric motor for the transmitting member to be inserted therein. The groove transmits a rotary torque of the electric motor to the rotary shaft by contacting an inner surface of the groove and the transmitting member and has an opening width along a rotary direction of the rotary shaft which is larger than the width of the transmitting member. The groove and the transmitting member produce an impact torque when the electric pump is started.

摘要： In a reciprocating compressor, an adequate lubricating effect is ensured for a sliding surface between a piston and a cylinder bore, and the leakage of a refrigerant for discharge is prevented. After a lubricating oil mixed within the refrigerant is separated by an oil separator 23 on a discharge side, the separated lubricating oil is guided via an oil supply hole 29 in a cylinder block 1 to the sliding surface between the cylinder bore 12 and the piston 13 that reciprocates within the cylinder bore 12 thereof in order to lubricate the surface. In this reciprocating compressor, the intermediate axial portion of the outer circumference of the piston 13 has a small diameter in order to define an oil sump 30. The oil sump 30 is configured so as not to directly communicate with a drive chamber 7, and oil always collects within the oil sump 30.

摘要： An improved scroll compressor having a movable scroll that orbits without being inclined. The compressor has a fixed scroll formed in the housing. The movable scroll is accommodated in the housing and mates with the fixed scroll. The movable scroll is driven by a drive shaft via a crank mechanism. A flange is formed at the periphery of the movable scroll and lies perpendicular to the drive shaft. A groove is formed in the housing. The groove is slightly wider than the thickness of the flange. The flange is slidably accommodated in the groove. Support holes extend through the flange. A pin is supported in each support hole. The ends of each pin are received in guide holes. Since engagement of the flange and the groove prevents the movable scroll from being inclined, the pin is maintained parallel to the guide holes and follows the wall of the guide holes. As a result, uneven wear of the pins and the guide holes is avoided.

摘要： A rotary shaft is rotatable relative to a motor rotor. A first end face of the motor rotor is exposed to the outside of a stator. A hammer portion is provided at the first end face. The hammer portion is configured to be movable as the motor rotor rotates. A collision portion rotating integrally with the rotary shaft is configured to collide with the hammer portion. The allowance space between the collision portion and the hammer portion allows the hammer portion to be move relative to the collision portion. Therefore, the electric pump is capable of detaching a rotor from a pump chamber without increasing the size of the pump.

摘要： A compressor is provided for guiding lubricating oil separated from the discharged refrigerant by an oil separator to a radial bearing supporting a drive shaft through an oil supply hole. A rotating member that rotates together with the drive shaft is provided adjacent to the radial bearing on the drive shaft, and lubricating oil is supplied to the radial bearing via a gap between an external surface of the rotating member and an internal surface of a circular hole that supports the rotating member. An oil support groove, which alternately communicates with the oil supply hole and the discharge hole every time the rotating member rotates once, is provided on the external surface of the rotating member, and the lubricating oil flowing in from the oil supply hole is intermittently discharged into a drive chamber via the groove and the discharge hole.
