Abstract: A rolling rotor motor/compressor is provided with an external rotor/piston which coacts with a bore/cylinder in the housing and one or more vanes to define a rolling piston compressor. Thus, the stator does not form a part of the compression chamber. The compressor can be readily designed for two cylinder or two stage operation.

Abstract: A connector block operatively engages the pins of a terminal assembly in a frictional or other mechanical relationship such that the connector block is securely held in place. When held in place, the connector block overlies the pins such that they cannot be dislodged from the terminal assembly. Connectors located in the connector block provide frictional engagement with the pins while affording electrical access to the terminal assembly.

Abstract: An electric terminal comprising a body, a plurality of terminal pins and terminal nuts, a pin retainer, and retainer connecting apparatus releasably connecting the pin retainer to the terminal body. The terminal pins longitudinally extend through the body, and the terminal nuts encircle and engage upper portions of the terminal pins and are held thereby in pressure contact agains the body. The pin retainer longitudinally extends between terminal pins to insulate electrically the pins from adjacent pins, and transversely extends over the terminal nuts to maintain the terminal nuts and the terminal pins in place. The terminal pins longitudinally extend above the transversely extending portion of the pin retainer to provide access to the terminal pins.
