Abstract
The present disclosure provides a flow control valve for controlling the flow of a cleaning media, such as controlling the flow of cleaning media to a nozzle positioned to distribute the cleaning media to a vehicle surface. The flow control valve includes a plunger and a flexible diaphragm which operate to open and close the a fluid passage through the valve. Vehicles and systems incorporating a flow control valve are also provided.
Claims15
A dual valve flow control assembly for supplying cleaning media to nozzles for cleaning a vehicle surface, comprising:
- a first pilot-operated valve comprising a solenoid actuator and a flexible diaphragm controlling a flow of cleaning media through a fluid passage between a first valve inlet and a first valve outlet;
- a second pilot-operated valve comprising a solenoid actuator and a flexible diaphragm controlling a flow of cleaning media through a fluid passage between a second valve inlet and a second valve outlet;
- and
- a housing defining an interior space and comprising the first valve inlet, the second valve inlet, the first valve outlet, and the second valve outlet;
- wherein the solenoid actuators are received in the interior space of the housing, and wherein the housing comprises a first face on which the first and second valve inlets are disposed and a second face on which the first and second valve outlets are disposed;
- and
- an adaptor comprising:
- a liquid inlet configured for fluid communication with a source of pressurized liquid;
- a liquid outlet in fluid communication with the first pilot-operated valve;
- a liquid passage between the liquid inlet and the liquid outlet;
- an air inlet configured for fluid communication with a source of pressurized air;
- an air outlet in fluid communication with the second pilot-operated valve;
- and
- an air passage between the air inlet and the air outlet;
- and
- a quick connect coupling between the adaptor and the housing whereby the liquid and air outlets can be quickly connected and unconnected to the first and second pilot-operated valves;
- and
- wherein the adaptor is received on the first face of the housing, with the liquid outlet of the adaptor removably inserted into the first valve inlet and the air outlet of the adaptor removably inserted into the second valve inlet.
