<p>The pneumatic circuit switch is esp. for venting vacuum circuits. The switch housing has a spring loaded plunger with a radially acting flexible closure component. The sealing effect between the closure component has no effect on the switch actuating forces. Between the two flow openings (5, 14) is a sleeve (11) which acts in conjunction with the closure part (8) in the valve first position. The sleeve is formed integrally with the housing and it has guide faces (12), for the closure element (8) at its one end.</p> |
