Abstract
The present disclosure provides a power tool including a housing and a hydraulic drive assembly at least partially supported in the housing. The housing includes a handle that supports a switch that activates the tool. The hydraulic drive assembly includes a pump assembly operably coupled to the motor assembly, a reservoir configured to contain hydraulic fluid in fluid communication with the pump assembly and in which a baffle is supported, a cylinder in fluid communication with the pump assembly which supports an auto-return valve therein, and a piston disposed in the cylinder and biased to a first position by a piston spring. The pump assembly includes a manifold housing that at least partially defines an inlet passageway that fluidly communicates the pump assembly and the cylinder and supports an inlet check valve.
