Abstract
A pop-up sprinkler has a diaphragm-type valve in the lower end thereof which is actuated by a remote pilot valve. The pilot valve may be either solenoid actuated, or hydraulically actuated by a suitable valve actuator component. In a first embodiment an upwardly opening valve actuator component assembly housing communicates with a hollow wire and hose housing. The wire and hose housing connects to the side of the cylindrical outer body of the sprinkler to position a lid of the valve actuator component assembly housing at surface level, but outside a circular ground support flange connected to the sprinkler body. In a second embodiment, the housing is situated so that the lid effectively forms part of the circular ground support flange. The valve actuator component assembly housing may contain, for example, a pilot valve coupled to a solenoid, and a regulator. The pilot valve and regulator are connected through hoses to the sprinkler body. When the solenoid fails it can be easily replaced by opening the lid of the valve actuator component assembly housing and pulling out the solenoid, without having to excavate and remove the sprinkler.
