<p>The valve has overflow valves (14, 16, 18) provided in conduits guiding to compressed air outlet. Bypass-non-return valves (42, 44) and nozzles (46, 48) are provided parallel to valves (14, 16), so that a throttled flow bypassing the valves (14, 16) is provided to the compressed-air outlet. The nozzles are integrated in the valves (42, 44). An air vent conduit (50) has a non-return valve (52) to permit the flow from an outlet supply of the valve (18) to an inlet supply of the valves (14, 16) and to stop reversal flow.</p> |
