摘要： A roots type fluid machine includes suction and discharge ports, rotary shafts and a pair of rotors. The rotor has a number n of lobe and valley portions with apex and bottom ends. The lobe portions are located on imaginary lines extending radially from an axis of the rotary shaft. The outer surface of each one of the rotors is generated by rotating an outline of the rotor including an arc and involute and envelope curves around and moving the outline in the direction of the axis. The arc has a radius R and a center located on the imaginary line. The involute curve is formed by an imaginary base circle having a radius r and a center located on the axis. The envelope curve is formed by an arc having a radius R. The number n is four or more. A torsional angle β is over 360/n degrees.

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 compressor includes a housing member having a through hole. The compressor includes a conductive portion through which external electricity is supplied to a motor mechanism. The conductive portion has a lead extending from the motor mechanism, and a connector terminal. The connector terminal is connected to the lead to permit the external electricity to be conducted to the lead. The connector terminal is attached to the through hole such that a joint between the lead and the connector terminal is located in the through hole to face inward of the housing member. A viscoelastic insulating material fills the through hole. Therefore, the compressor ensures reliable insulation of the terminal from a housing member.
