Abstract (en)
[origin: EP0074496A1] 1. Valve arrangement, especially for pressure die casting machines, with the following features : - arranged in a valve housing (1) is a main valve with a valve cone (6), a control piston (10) and a stroke-limiting stop (25) ; - the stroke-limiting stop (25) can be adjusted by means of a drive mechanism (26, 34), which comprises a threaded bush (26) and a support thread (48) arranged on the valve housing (1) ; - a control valve device (50 to 56), which also contains throttle devices (56), is connected by at least one control line (61) to the main valve, so that the valve cone (6) of the latter can execute a delayed or a quick movement ; characterised in that the threaded bush (26) has pressurised surfaces (27, 30, 33), on which counteracting displacement forces - in the support direction or in the release direction - develop onto the threaded bush (26), the relative size of which displacement forces to one another changes with every switching cycle of the valve cone (6).
