摘要： A pressure and vacuum pump including at least two diaphragm pump heads for providing vacuum and pressure simultaneously. The dual function pump reduces number of required pumps, is traditionally quieter, and enables the system to run at a lower duty cycle. A drive in the pump housing causes a connecting rod to oscillate a diaphragm to move up and down thereby causing air to be either drawn into an inlet or forced out via an exhaust.

摘要： The present invention discloses a system comprising an actuation valve for receiving a first pressurized fluid, a piston in communication with the actuation valve, and a flow restrictor for controlling the flow of a second pressurized fluid from the piston. The flow restrictor may vent to ambient pressure and the piston may act as a pinch valve on at least one of an irrigation line.
