A hydraulic pump and a method of operating a double acting hydraulic pump is provided. The method includes retrieving a current operating pressure from memory of a controller, controlling a pump assembly to pump hydraulic fluid from a bladder through one of two work ports to a hydraulic tool at the current operating pressure, and updating the current operating pressure based on input from a user interface.

Hydraulic pump with electronic adjustable pressure setting

A blind rivet nut-setting tool for setting a rivet nut including a housing having an anvil, a pull stud for engaging the rivet nut, and an output shaft defining a drive axis. The tool includes a motor defining a motor axis. The motor is configured to transfer torque to the output shaft to rotate the pull stud about the drive axis. The tool includes a clutch mechanism that is disposed between the motor and the output shaft. The clutch mechanism is moveable between an engaged state, in which a reaction torque exerted on the pull stud is below a predefined torque threshold, and a disengaged state, in which a reaction torque exerted on the pull stud is equal to or above a predefined torque threshold. The tool includes a pull mechanism that is driven by the motor and capable of translating the pull stud along the drive axis.

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.

Power tool hydraulic system

Embodiments of the invention provide a die retainer for use in a tool. The die retainer can include a ram head, a release button, and a die pin. The ram head includes a die cavity and a pair of lateral sides on opposing sides of the die cavity. The release button can extend through a release button hole formed in the ram head hand include opposing ends that extend past each of the corresponding pair of lateral sides. The die pin extends through a die pin cavity that intersects the release button hole. The die release button can be actuatable from either of the opposing ends to retract the die pin from the die cavity.
