Abstract
A hydraulic hammer assembly includes a housing, a work tool, a fluid inlet, a fluid outlet, and a filter. The work tool is movable within the housing. The fluid inlet is configured to receive a hydraulic fluid for driving the work tool, and the fluid inlet is upstream of the work tool. The fluid outlet is for discharging the hydraulic fluid from the housing, and the fluid outlet is downstream of the work tool. The filter is positioned within the housing between the fluid inlet and the work tool.
Claims20
A hydraulic hammer assembly, comprising:
- a housing;
- a work tool, wherein the work tool is movable within the housing;
- a fluid inlet configured to receive a hydraulic fluid for driving the work tool, wherein the fluid inlet is upstream of the work tool;
- a fluid outlet for discharging the hydraulic fluid from the housing, wherein the fluid outlet is downstream of the work tool;
- and
- a filter, wherein the housing defines an inlet passage between the fluid inlet and the work tool, wherein the filter is positioned within the housing inlet passage between the fluid inlet and the work tool, such that hydraulic fluid flows from the fluid inlet, through the filter, and to the work tool.
