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： 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 motor-driven Roots compressor includes a drive shaft driven by a motor and a driven shaft connected to a drive shaft through a timing gear. A pair of rotors is respectively fixed to the drive shaft and the driven shaft. The rotors are rotated so that the compressor draws and discharges working fluid. The compressor also includes a casing having a plurality of shells which define a motor chamber for accommodating the motor, a gear chamber for accommodating the timing gear and a rotor chamber for accommodating the pair of rotors. A refrigerant passage is formed in at least one of the shells of the motor chamber and the gear chamber for flowing the working fluid therein. At least one of the motor and the timing gear is cooled by the working fluid in the refrigerant passage.

摘要： A fluid machine includes a motor and a motor housing. The motor housing defines a motor chamber for accommodating the motor. The motor chamber is filled with inert gas. A rotor rotates in accordance with rotation of the motor. A pump housing defines a pump chamber for accommodating the rotor. A dividing wall is located between the pump housing and the motor housing. The pump housing and the motor housing are attached to each other via the dividing wall. Therefore, water is prevented from being generated in the motor chamber even if fluid that contains hydrogen leaks from the pump chamber to the motor chamber.

摘要： A starting system for a pump includes a driving motor, an electric source, a selector switch, a starter sensor, a temperature sensor and a control unit. The selector switch is located between the driving motor and the electric source for reversing polarity of the electric power supplied from the electric source to the driving motor. The starter sensor senses whether or not the driving motor has been started. The temperature sensor senses a temperature. The control unit operates the selector switch so as to repeatedly give the driving motor indications of reverse rotation and normal rotation in a case where the starter sensor does not sense that the driving motor has been started even if the control unit operates the selector switch so as to give the driving motor the indication of normal rotation in a state where the temperature sensed by the temperature sensor is below a preset temperature.
