<p>The present invention comprises in short a device in the form of a tool for unloading pressure in hydraulic systems, said device including tubular housing (2) with a hydraulic liquid collection chamber (5). Preferably at either end of the housing (1) there is a male or female coupling half (17) for connection to a coupling half (20) in a hydraulic system. The coupling half (17) surrounds an actuating member (11), which is axially displaceable in relation to the coupling half (17), from a retracted position to an outward position, in the latter for actuating a valve plunger (21) in the connected coupling half (20) such as to open the valve and release pressure.</p> |
