FLUID-OPERATED TIME-DELAY RELAY

摘要

FIELD: agricultural engineering. SUBSTANCE: fluid-operated time-delay relay has a distributor. The distributor is provided with a spring-loaded membrane. The membrane has a rest. A float of the relay is provided with a tube for water with a clip. The membrane rest and the clip are in mesh. The time- delay relay switching mechanism is a chain with vessels mounted above and below the float chamber. The water inlet hole is opened by rests secured on the chain as they come in mesh with arch-shaped feelers. The feelers are provided with counterweights for operation with the forward and reverse movement of the chain. EFFECT: higher reliability.
