Abstract

In a quick-acting valve with a diaphragm-controlled permanent magnet (Fig. 2), the diaphragm 3 is fastened between housing parts 1 and 2 (resting flat on one another) by means of screws 7 onto a housing bottom part 20 with inserted valve insert 15 and 19 and antistatic sealing plate 14 placed in between. During increasing pressure, which is fed via the hose connection nipple 13, the diaphragm 3 lifts the permanent magnet 5 inserted in the magnet housing 4 from the metallic valve head 16 (in the same plane) of the valve insert until the spring-loaded catch 10 to 12 inserted in the housing top part 1 engages in the groove 29 of the sleeve 9, which is fastened to the stem of the magnet housing 4 by means of screw 8. <IMAGE>
