摘要： A combined prime valve and electrical pressure control apparatus including a prime valve actuator, an electrical pressure control actuator, and a control housing containing the actuators, with each coupled to a single shaft having a cam assembly for selectively actuating the control apparatus to one of a prime mode and a spray mode and the electrical pressure control is operable within a range of pressure settings by movement of the shaft while the control apparatus remains in the spray mode. The actuators are oriented diametrically opposite and offset along an axis of the single shaft with respect to each other, and contact the cam assembly and respectively contact a lever for a prime valve and a pressure switch carrier. A setscrew in the carrier provides adjustment of the pressure at which the switch is actuated.
