摘要:
A water spraying system includes an engine, a pump driven by the engine, the pump including a pump inlet configured to be fluidly coupled to a water source and a pump outlet providing water at an increased water pressure, a sprayer fluidly coupled to the pump outlet, the sprayer including a flow restriction valve and a trigger for manipulating the flow restriction valve so that movement of the trigger selectively opens and closes the flow restriction valve, a flow sensor configured to sense a flow of water into the pump, and a controller coupled to the flow sensor. The controller is configured to turn off the engine following a set time period of sensed flow below a threshold flow.
