Abstract
A piston and cylinder assembly includes a housing defining a bore. A piston is sized to reciprocate in the bore. A first sealing member provides a sealing engagement between the piston and a wall of the bore. A first bushing, of a first material, is around a first portion of the piston toward a first end of the piston. A second bushing, of a second material, is around a second portion of the piston toward a second end of the piston. The first and second bushings guide the piston within the bore. The first material is different than the second material.

A piston and cylinder assembly, the assembly comprising:
- a housing defining a bore;
- a piston sized to reciprocate in the bore;
- a first sealing member providing a sealing engagement between the piston and a wall of the bore;
- a first bushing, of a first material, around a first portion of the piston toward a first end of the piston;
- and
- a second bushing, of a second material, around a second portion of the piston toward a second end of the piston, the first and second bushings guiding the piston within the bore, and the first material being different than the second material.
A piston and cylinder assembly, the assembly comprising:
- a housing defining a bore;
- a piston sized to reciprocate in the bore;
- a first bushing, of a first material, around a first portion of the piston toward a first end of the piston;
- a first sealing member, proximate the first bushing, providing a seal between the piston and a wall of the bore;
- and
- a second bushing, of a second material, around a second portion of the piston toward a second end of the piston, the first and second bushings guiding the piston within the bore, and the first material being different than the second material.
A piston and cylinder assembly, including:
- a piston sized to reciprocate in the bore;
- a first sealing member providing a seal between the piston and a wall of the bore;
- means for reducing side loads on the first sealing member generated during reciprocation of the piston in the bore.
