ABSTRACT:
TECHNICAL FIELD
This invention is concerned with improving the reliability and performance of distribution valves of the type employed to sequentially direct a fluid, such as water, to a plurality of pop-up cleaning nozzles in a swimming pool or spa.
BACKGROUND ART
This type of valve is well known in the prior art. One particularly successful version of the distribution valve is disclosed in U.S. Pat. No. 4,592,379 granted Jun. 3, 1986 to John M. Goettl for “Fluid Distribution Valve”. Many of the features disclosed in the Goettl patent are useful in the valve to which this application is directed and, hence, the Goettl disclosure is incorporated herein by reference.
The valve of the '379 patent can be improved upon.
SUMMARY OF THE INVENTION
In the Goettl '379 patent valve the valve actuating mechanism is driven by a turbine positioned above the inlet opening to the valve.
In accordance with this invention there is positioned in the valve inlet ahead of the turbine a flow control member which can be adjusted to alter the flow of fluid to the turbine. With the flow control member a service person can change the frequency at which the valve operates.
The flow control member is preferably removably mounted on the valve shut-off plate which is mounted on and seals with an inlet wall and a plurality of ribs extending outwardly from the inlet wall to the upstanding side wall of the base. The ribs partition the base into a plurality of outlet flow chambers. Further in accordance with this invention there is provided a wagon wheel-like gasket between the valve shut-off plate the inlet wall and the ribs to minimize fluid leakage between the outlet flow chambers.
