    Abstract: An electric compressor includes a housing, a refrigerant inlet port, a refrigerant outlet port, an inverter module, a motor, a drive shaft, clamping mechanisms, and a compression device. The refrigerant inlet port is coupled to the housing and configured to introduce the refrigerant to an intake volume. The refrigerant outlet port is coupled to the housing and is configured to allow compressed refrigerant to exit a discharge volume. The inverter module is adapted to convert direct current electrical power to alternating current electrical power. The motor is mounted inside the housing. The plurality of clamping mechanisms are spaced about the outer diameter of the motor and configured to constrain the motor within housing. The compression device, coupled to the drive shaft, receives the refrigerant from the intake volume and compresses the refrigerant as the drive shaft is rotated by the motor.

    Abstract: A side housing (111) for a rotary internal combustion engine, has: a side wall (14); a side plate (116) having a rotor-engaging side facing away from the side wall (14) and a back side (116B) opposite the rotor-engaging side and facing the side wall (14), the side plate (116) defining first threads (1160) located on the back side (116B), the first threads (116D) extending circumferentially around a central axis of the side plate (116); and a nut (117) rotatable relative to the side wall (14) about the central axis of the side plate (116) and axially locked to the side wall (14) relative to the central axis, the side plate (116) secured to the side wall (14) via a threaded engagement between the first threads (116D) of the side plate and second threads (117B) defined by the nut (117).
