ABSTRACT:
A single-sprinkler controller comprises a timer for the input of data of sprinkling time for the sprinkler, a motor electrically connected to and operatively controlled by the timer based on the data, a rotor disc with two ridges mounted on a first shaft rotatably mounted on a mount wall and drivable by the motor, a pivot member pivotably mounted to a mount wall, and a valve assembly. The valve assembly includes an enclosure with a chamber having a first open side mounted to and sealed by the mount wall and a second open side, an inlet conduit having a first inlet in fluid communication with a water supply provided outside the enclosure and a first outlet provided in the chamber, an outlet conduit having a second inlet in the first outlet and a second outlet in fluid communication to the sprinkler, a rear cover mounted to and sealing the second open side of the chamber, and a valve membrane provided in the chamber. The valve membrane is initially in a first status when neither of the ridges contact the pivot member, such that the inlet conduit is not in fluid communication with the outlet conduit, and the valve membrane is in a second status when one of said ridges contacts and urges the pivot member, such that the inlet conduit is in fluid communication with the outlet conduit.
