Title: Upstroke press pressure relief valve - has servo valve and throttling device working together with reversing piston valve
Inventor: BRUNNER RUDOLF
IPC: B30B15/18
Filed: 1977-04-20
Abstract: The valve in upstroke presses, for relieving pressure has a high pressure connection (HD), a low pressure connection (ND) an operating connection (A) and a return line (R). In the initial open position of the press the cylinder is fed with high and low pressure fluid from (HD) and (ND) via supply line (A), after passing non return valves (2, 3) and the press closes up rapidly. After reaching the closing position the pressure increases until at the preset pressure, the limiting valve (4) opens and the low pressure circuit is connected directly to the return line. The non return valve (2) closes. The line (A) is now supplied exclusively through the high pressure line (HD) while the non return valve (3) is open. For opening the press, the servo valve (15) is operated. Hereby the branch line (14a) is connected with the intermediate line (19) and the high pressure fluid flows through the reversing valve into branch line (10a) with built-in throttling device (21) so that the pressure relief becomes gradual.
