Hydraulic hammer having single piece seal assembly

A seal assembly for a hydraulic hammer, the seal assembly comprising:

• a seal carrier fabricated from a non-metallic material, the seal carrier having:
• a first inner annular recess;
• and
• a second inner annular recess positioned gravitationally lower than the first inner annular recess;
• a first unidirectional seal integrally molded onto surfaces of the first inner annular recess;
• and
• a second unidirectional seal integrally molded onto surfaces of the second inner annular recess.

A hydraulic hammer system, comprising:

• a frame;
• a piston;
• an accumulator membrane disposed external and co-axial to the piston;
• a sleeve disposed between the piston and the accumulator membrane;
• a valve located at an axial end of the accumulator membrane and inward of the sleeve;
• a sleeve liner disposed between the accumulator membrane and the sleeve;
• and
• a seal assembly having:
• a seal carrier co-axial with and located axially adjacent to the valve, the seal carrier being fabricated from a non-metallic material and having a first inner annular recess, and a second inner annular recess positioned gravitationally lower than the first inner annular recess;
• a first unidirectional seal integrally molded onto surfaces of the first inner annular recess;
• and
• a second unidirectional seal integrally molded onto surfaces of the second inner annular recess.
