ABSTRACT:
This invention relates to a foot operated control valve in which the water supply is automatically stopped as soon as a foot push button is released. It is not only convenient for use, but can also economize water consumption by means of auto start and stop fully under foot control. The control valve has a housing and a valve body. The valve body includes an inlet cylinder and an outlet cylinder with both cylinders integrally communicated by means of a channel. The inlet cylinder having an adjustment assembly to open or block the water inlet. The outlet cylinder has a spring, valve and sleeve, in which the valve is movable to block or open the valve inlet for stopping or allowing water entry into the outlet. The open/close function can be accomplished by a valve opened by foot or closed by resilience of a spring to ensure that the use and water economization can be accomplished. The user is not required to control the faucet by hand, thereby eliminating its risk of water waste as a result of failing to shut off the faucet or failure to close fully because of faucet malfunction.
