The present disclosure provides a telescoping device for cleaning a vehicle surface. The telescoping device includes an extendable piston moveable from an inactive position to active position at a predetermined extension pressure. The piston includes a supply tube, a cleaning fluid outlet provided at a distal end of the supply tube, and a check valve comprising a cracking pressure that is greater than the predetermined extension pressure. Vehicles and systems incorporating a telescoping cleaning device are also provided.

A sprinkler head nozzle assembly in accordance with an embodiment of the present invention includes an adjustable nozzle operable to extend and reduce an arcuate opening wherein the size of the arcuate opening indicates the arc of coverage of the sprinkler head nozzle assembly and a rotating distributor, mounted on a central shaft extending through the housing and the nozzle member, and operable to deflect a flow of water from the arcuate opening out of the nozzle assembly.

A sprinkler extension device is disclosed to adjust a height of an existing pop-up sprinkler installed in the ground. An example sprinkler extension device includes an extension riser configured to mate on a first end to a sprinkler riser. The extension riser is further configured to mate on a second end to a spray cap of the existing pop-up sprinkler installed in the ground. The example sprinkler extension device also includes an extension coupling configured to mate on a first end to a sprinkler housing. The extension coupling is further configured to mate on a second end to a sprinkler head of the existing pop-up sprinkler installed in the ground.

A sprinkler can include a turbine, a nozzle, a gear drive and a reversing mechanism. The gear drive and the reversing mechanism rotatably couple the turbine and the nozzle. The gear drive can shift a direction of rotation of an output stage that is coupled to the reversing mechanism. The sprinkler can include at least one arc adjusting gear that moves and arc adjusting tab to contact a shift arm to cause the shifting mechanism to change direction. The arc adjusting gear can engage with the arc tab for adjusting the arc setting and disengage from the arc tab for normal operation.

A nozzle device 1 includes a main body 10 that is formed of a main-body first member 11 and a main-body second member 22 and that has an internal accommodation space 21 in which members are accommodated, a movable nozzle portion 30 that is accommodated in the accommodation space 21, and a coil spring 2 that is disposed between the movable nozzle portion 30 and the main body 10. When air is supplied to a main-body flow-path portion 23 from below, the flow path of the air is changed by the Coanda effect in an air guiding portion 27 such that the air flows along the air guiding portion 27, and the air flows into a gap between an air receiving portion 36 and the air guiding portion 27 and is guided to the air receiving portion 36. The air is pressurized in the air receiving portion 36 and pushes up the movable nozzle portion 30.

This disclosure provides an improved nozzle assembly. The nozzle assembly includes a housing having an inlet for directing media (e.g. cleaning fluid) into the housing, and a nozzle core rotatably coupled to the housing. The nozzle core includes a sprayer shaft and a vane coupled thereto. The sprayer shaft defines a peripheral outlet, and is adapted for passage of media from the housing through the outlet. The vane is adapted to receive media from the inlet to rotationally bias the nozzle core in a first direction and radially orient the outlet to an activated position. The nozzle assembly further comprises means for rotationally biasing the nozzle core in a second direction opposite the first to radially orient the outlet to a home position different than the activated position. A system comprising the nozzle assembly, and methods of using each of the same, are also disclosed.
