Abstract

The level of water in household equipment such as washing machine is controlled by sensing pressure reduction in tube connected to the recipient. A threshold level is set at which supply valve is operated. A depressurisation generator (1) is connected downstream from an electrically controlled valve(2) and water supply tap(R). A constant pressure valve(3) connected(6) to the depressurising tube(5) from lower section of the recipient (C) controls the supply valve(2) as head(h) of water varies. This section of tube is also connected to the recipient and its outlet defines the level(N) at which control is effected.
