Abstract
A valve for dispensing a liquid includes a housing, an internal liquid passage extending through the housing, a valve seat, a valve member movable between a closed position engaging the valve seat and an open position disengaging the valve seat, and a control member controlling movement of the valve member, which is movable between a first position in which it engages the valve member in its closed position, a second position in which the valve member is in its open position but still engaging the control member and a third position in which the valve member is in its open position and out of engagement with the control member. At least one air passage connects the outside of the valve with the internal liquid passage. The at least one air passage is closed in the first and second positions of the control member and is opened in the third position.
