Abstract: An electric compressor is provided in which the connection strength between lead terminals from a motor and an inverter circuit section is improved. The electric compressor 1 is constituted by electrically connecting lead terminals 24 to 26 of a motor and an inverter circuit section 3 for supplying power to the motor by a motor side connection terminal 28. The inverter circuit section 3 is protrusively provided with terminal connection portions 19 to 21 each having a screw groove portion. The motor side connection terminal 28 has a flat plate terminal portion. The flat plate terminal portion is fixed to the inverter circuit section 3 by a nut 91 screwed into each of the screw groove portions of the terminal connection portions 19 to 21 and electrically connected to the inverter circuit section 3 in that state.

Abstract: There is provided an electric compressor in which the connection strength between an inverter circuit section and an electrical circuit section connected thereto by a connection terminal is improved. An inverter circuit section (3) includes an inverter control board (17) and a resin-molded sleeve assembly (18). In the sleeve assembly, a sleeve (32) and a terminal connection portion (23) are integrally resin-molded in a state in which a screw groove portion is protruded. The inverter control board (17) and a filter side connection terminal (71) of a filter circuit section (4) are fastened together to the terminal connection portion with a nut (92) screwed into the screw groove portion, whereby the inverter control board 17 and the filter circuit section 4 are electrically connected.

Abstract: Provided is a variable displacement compressor capable of preventing intrusion of foreign matter into a second control valve. A variable displacement compressor 100 is equipped with a first control valve 300 controlling the opening degree of a supply passage 145, a check valve 350, a second control valve 400 controlling the opening degree of a discharge passage 146, and a back-pressure relief passage 147. The second control valve 400 has a back-pressure chamber 410 communicating with an intermediate supply passage 145b1, a valve chamber 420 in which a valve hole 103d and a discharge hole 431a are open and which constitutes a part of the discharge passage 146, a dividing member 430 dividing the back-pressure chamber 410 and the valve chamber 420 from each other, and a spool 440. In a state in which the first control valve 300 closes the supply passage 145 and in which a valve seat side end surface 442a of a valve portion 442 of the spool 440 is spaced away from a valve seat 103f to a maximum degree, an end wall side end surface 442b of the valve portion 442 abuts an end wall 432 of the dividing member 430, whereby communication between the valve chamber 420 and the back-pressure chamber 410 via a through-hole 432a of the end wall 432 is cut off.
