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.
Claims10
A fluid compressor comprising
- a motor having an output shaft,
- a piston housing having in it at least one recess,
- a sleeve located in said recess, said sleeve having an axis extending transverse to said output shaft,
- a piston located and reciprocable in said sleeve upon rotation of said output shaft,
- bracket means for mounting said motor interposed between said motor and said piston housing,
- resilient spring means acting between said bracket means and said sleeve and applying a biasing force against said sleeve acting in a direction transverse to the axis of said sleeve and holding said sleeve in the recess in said piston housing.
A compressor for fluids comprising:
- a motor including an output shaft rotatable about a longitudinal axis;
- a piston housing into which said output shaft extends, said piston housing having a surface that faces the motor and that defines a recess in said piston housing;
- a tubular sleeve located in the housing recess and having a longitudinal axis extending transverse to and in a common plane with the axis of said output shaft;
- a piston reciprocable in said sleeve;
- and
- spring means engaging an outer surface of said sleeve and pressing said sleeve into engagement with said surface that defines said recess, said spring means acting in a direction generally parallel to the axis of said output shaft and holding said sleeve in said recess.
