   PATENT CLAIMS:
1. Control for hydraulic drawing presses with two-seat main valve and single-seat retraction and regulating valve housed in a common housing, characterized in that the main valve (12) and the retraction valve (13) prevent sudden rise by means of appropriate braking devices and thereby impacts on the press and the control mechanism can be prevented.

Claims (1)

2. Steuerung nach Anspruch l, dadurch gekennzeichnet, dass das Hauptventil (12) oberhalb des oberen Ventilsitzes eine Eindrehung besitzt, in welcher eine Anzahl radial verlaufender Löcher (45) gebohrt sind, die in eine Ausbohrung des oberen Teiles des Ventilkegels einmünden. 2. Control according to claim l, characterized in that the main valve (12) above the upper valve seat has a recess in which a number of radially extending holes (45) are drilled which open into a bore in the upper part of the valve cone. 3. Steuerung nach Anspruch l, dadurch gekennzeichnet, dass oberhalb der Rückzugventils (13) ein hydraulischer Bremszylinder (41) angeordnet ist, der in zwei Kammern (42, 43) abgeteilt ist, die durch einen Kanal (44) miteinander in Verbindung stehen. 3. Control according to claim l, characterized in that a hydraulic brake cylinder (41) is arranged above the retraction valve (13), which is divided into two chambers (42, 43) which are in communication with one another through a channel (44).
