ABSTRACT:
An improvement to the hydraulic power apparatus for hydraulic presses is provided, wherein the seals and various gaskets for containing the hydraulic fluid in the press has an enclosed container substituted therefor. This enclosed container, in communication with hydraulic fluid reservoirs, provides the pressure for the ram in the hydraulic press. The container is inflatable with the pressure on the hydraulic fluid, but which fluid is never in direct contact with any of the structural mechanisms comprising the hydraulic power apparatus. The hydraulic power apparatus, hence, can be modified to increase the dimension of the ram to remove the gasket mechanisms and to provide an installation hatch which facilitates serviceability to the inflatable container.
