Claims16
A hydraulic circuit component comprising at least one component having a first surface and a second component having a second surface, wherein the first and second surfaces engage in sliding contact during operation of the component, wherein at least one of the first and second surfaces comprise a non-metal crystalline material;
- the hydraulic circuit component further comprising a first seal plate comprising the first surface, a second seal plate, and a carrier haying a first sealing element comprising the second surface contacting the first surface and a second sealing element contacting the second seal plate, wherein the first and second sealing elements include the non-metal crystalline material at least at the contact surface of the first surface and the second surface.
A hydraulic circuit component comprising at least one component having a crystalline first surface and a second component having a second surface, the crystalline first surface and the second surface biased toward one another by a biasing force, and configured to move with respect to one another while maintaining contact of at least portions thereof during movement thereof with respect to each other,
- the hydraulic circuit component, further comprising a first seal plate surface comprising the first surface, a second seal plate surface, and a carrier having a first sealing element comprising the second surface contacting the first seal plate surface and a second sealing element contacting the second seal plate surface, wherein the first and second sealing elements include the crystalline material at least at the contact surface thereof with the first seal plate surface and the second seal plate surfaces.
