Controlled feed pistol for setting hydraulic props

摘要

The control unit (10) is formed by a through passage valve (20) with spring-loaded sealing cone (21), a venting valve (28) with sealing body (29) and an externally influenced pressure pin (13). A thruster (40) is displaceable in the pistol housing and connects the sealing body with the sealing cone. The thruster is formed as a control socket (41) with control bores (43, 44, 46).
