Abstract: A sealed terminal device for a motor-driven compressor has an electrically insulating terminal holder (12) to be attached to the housing wall (2a) of the motor-driven compressor, a plurality of sealed terminals (18) held in the terminal holder (12), for penetrating the housing wall (2a) with play to the housing wall (2a), and a groove (40) or cavity (38) formed in the terminal holder (12) to increase a creepage distance for insulation between the sealed terminals.

Abstract: An inclined plate-type compressor includes a cylinder head, a discharge chamber having an annular shape and disposed along an outer circumferential portion of the cylinder head, a suction chamber disposed at a central portion of the cylinder head, a valve plate including discharge ports, and a discharge valve including reed valve-type valve bodies disposed in the discharge chamber. Each valve body opens and closes a corresponding discharge port, and each valve body extends in a circumferential direction of the discharge chamber and is oriented along the annular shape of the discharge chamber. Because each valve body extends in the circumferential direction of the discharge chamber, the length of each valve body may be increased as compared with that in known compressors, wherein the valve body extends in the radial direction over the width of the annular discharge chamber. Consequently, stress, which is generated at a root portion of each valve body when the valve body is opened or closed, may be reduced.
