ABSTRACT:
An air compressor including a motor, a motor housing, a piston assembly and a piston housing is disclosed. A bracket is located between the motor housing and the piston housing. The piston assembly includes pistons which reciprocate within sleeves upon rotation of a cam driven by the motor. The sleeves are received in U-shaped recesses in the piston housing. The open end of the U-shaped recesses are closed by the bracket. The bracket has tangs which act as springs to urge the sleeves firmly into the housing. The tangs accommodate variations in the dimensions of the housing and the sleeves, as well as provide contact with the sleeves for heat transfer.
