摘要： A compressor includes a housing, a rotary shaft, a pulley, an electric motor, a pulley one-way clutch, and a motor one-way clutch. The shaft is rotatably supported by the housing. The pulley is operably connected to the shaft and includes a power transmission portion. When power is transmitted from a vehicular engine to the power transmission portion, the pulley is rotated. The electric motor rotates the shaft and includes a rotor, which is operably connected to the shaft. At least part of the electric motor overlaps the power transmission portion in the axial direction of the shaft. The pulley one-way clutch is located between the pulley and the shaft and selectively permits and prevents power transmission between the pulley and the shaft. The motor one-way clutch is located between the rotor and the shaft and selectively permits and prevents power transmission between the rotor and the shaft.

摘要： A housing of a compressor supports a rotary shaft. The rotary shaft is coupled to a pulley with a pulley one-way clutch and is coupled to a rotor of an electric motor with a motor one-way clutch. The pulley is supported by the housing with a pulley bearing. The electric motor overlaps a power transmission portion in the axial direction of the rotary shaft. At least two of the bearing, the pulley one-way clutch, the motor one-way clutch, and a brush device of the electric motor overlap each other in the axial direction of the rotary shaft. As a result, the size of the compressor is reduced in the axial direction of the rotary shaft.

摘要： An electric compressor includes a rotary shaft that is driven by an electric motor. The motor generates driving torque. Pistons compress gas in accordance with rotation of the rotary shaft. During one turn of the rotary shaft, the times when the net load torque generated by the pistons is minimum and the times when the driving torque of the motor is minimum occur at substantially the same rotation angles of the rotary shaft. Also, during one turn of the rotary shaft, the times when the net load torque is maximum and the times when the driving torque of the motor is maximum occur at substantially the same rotation angles of the rotary shaft. The driving torque is always greater than the net load torque. Therefore, the motor need not be large to generate sufficient torque.

摘要： A wave cam type compressor is provided. The compressor has a wave cam body mounted on a rotary shaft for integral rotation and pistons operably contacting said cam body by way of shoes. The shoes are moveable relative to the cam body according to the rotation of the cam body. The shoes move on predetermined paths on cam surfaces of the cam body. The rotation therewith of the rotary shaft is converted into a reciprocation movement of the pistons between top dead center and a lower dead center in cylinder bores to compress fluid supplied into the cylinder bores. Each cam surface has a contour matching the locus of a predetermined smooth two-dimensional imaginary curve when the curve is translated from its plane in the direction perpendicular to the plane. A first portion is provided on the cam surface to drive the piston to the bottom dead center and a second portion is provided on the cam surface to drive the piston to the top dead center. The second portion has a greater radius of curvature than the first portion.

摘要： Disclosed is a compressor having a plate rotatable about an axis of a rotary shaft and a piston connected to the plate. The plate causes the piston to reciprocate between a top dead center and a bottom dead center of its stroke in accordance with the rotation movement of the plate. Cam surfaces are provided on the plate for actuating the piston. The cam surfaces have first portions for driving the piston toward the top dead center, and second portions for driving the piston toward the bottom dead center. Transmission members are interposed between the piston and the cam surface for transmitting the rotational movement of the plate to the piston. The first and second portions cause the transmission members to follow on the cam surfaces. At lease one of the first and second portions are arranged to have a normal line extending obliquely to the axis of the rotary shaft for constant contact between the transmission members and the one of the portions.
