摘要： A flow control valve, comprising a flow controlling valve configured to deflect from a generally planar posture to an increasingly nonplanar posture responsive to a relative increase in pressure difference and flow across the valve element; and a support element including a support structure supporting the valve element in its undeflected state; at least a first contact surface recessed from the support structure and configured to engage the valve element only when the valve element is deflected; and a flow passage wherein an effective flow-through volume through the at least one opening and the flow passage decreases as deflection of the valve element increases.

摘要： A flow control valve is provided. According to one aspect of this disclosure, the flow control valve includes a valve element and a support element. The valve element is configured to deflect responsive to a change in pressure difference across the valve element. The support element cooperates with the valve element to present an effective flow-through area that changes as the valve element deflects. The amount of relative engagement between the valve element and the support element changes as the valve element deflects. External vibration causes the valve element to vibrate to reduce stiction or ice buildup.

摘要： A control system is disclosed having at least one spray head, a fluid pump, and a power converter driving the fluid pump. The control system may also have an interface device to receive at least one parameter associated with a desired fluid delivery event, a pressure sensor configured to generate a first signal, a travel speed sensor configured to generate a second signal, and a controller. The controller may be configured to determine a desired fluid pressure based on the at least one parameter, and determine a control command for the power converter based on the desired fluid pressure. The controller may be further configured to determine a feedforward gain parameter based on the at least one parameter and the second signal, determine a feedback gain parameter based on a difference between desired and actual fluid pressures, and adjust the control command based on the feedforward and feedback gain parameters.
