Abstract
A hydraulic compression tool having a frame, a hydraulic fluid reservoir on the frame, a ram movably connected to the frame, a conduit system in the frame between the reservoir and the ram, a pump provided in the conduit system, a mechanical actuator provided in the conduit system for contacting the ram, and a bypass valve in the conduit system between a rear end of the ram and a channel of the conduit system to the rear end of the mechanical actuator. The conduit system is adapted to conduit fluid from, the pump against both the rear end of the ram and a rear end of the mechanical actuator. The bypass valve is located, at least partially, in a housing member of the mechanical actuator.
