A body having a channel therein in which a flow valve is movably mounted. An inlet communicating with the channel near one end thereof, and an outlet communicating with the channel spaced from said inlet. The flow valve has a head near the end of the channel in communication with the inlet and adapted normally to engage a seat in the channel to close the latter, a stem of smaller cross section that the head, and a guide portion remote from the head and slidably fitting in the channel. Means for moving the valve to move the head thereof off the seat to permit water to flow from the inlet past the head to the outlet, said water gradually moving the head back on the seat.

Flush valve apparatus comprising: a valve body; a channel formed in said body, an inlet in communication with the channel near one end thereof, an outlet in communication with the channel and spaced from said one end, a flow valve in channel having a head, a stem of smaller cross section than the head and a guide portion that is a close, slidable fit in the channel and remote from the head, a valve seat in the channel between said one end and the outlet, said valve being reciprocal in the channel between a closed, rest position in which the valve head is located on the valve seat to a second position in which the head is in the vicinity of said one end, the flow valve being adapted to ensure that, in use, liquid can pass the head and out through the outlet at all positions except the closed position, and means to permit movement of the valve to move the head off the valve seat, whereby, in use, when the valve is moved to said second position liquid can pass from the inlet to the outlet and simultaneously move the valve gradually back to the closed, rest position to stop passage of liquid through the outlet.
