Hand-held pulling and compression device and hydraulic actuator

Abstract

The invention relates to a hand-held pulling and compression device and a hydraulic actuator for a hand-held pulling and compression device for driving hydraulic tools, with a housing body having a working chamber filled with hydraulic fluid, a hydraulic piston arranged in the working chamber to be displaceable between a starting position and an end position and a hydraulic tool connection with a hydraulic channel connected to the working chamber and having a self-closing valve. In order to provide a hydraulic actuator for an electro-mechanically driven hand-held pulling and compression device and a hand-held pulling and compression device which enables hydraulic tools to be driven in addition to electro-mechanically driven pulling and pressing tools, it is provided that on the hydraulic actuator the housing body has a connecting section for detachably fixing the hydraulic actuator to a connection section of the pulling and compression device and the hydraulic piston has a coupling section for connection to a drive element of the pulling and compression device which is adjustable relative to the connection section.
