摘要:
A diaphragm valve module is mounted in the lower end of the outer housing of a pop-up rotor type sprinkler for controlling the flow of water through an inlet in response to actuation of a valve actuator component. A resilient deformable semi-circular snap ring is mounted on top of the module and has a pair of opposing peripheral annular portions. Upon removal of the sprinkler riser, the snap ring can be disengaged from an annular groove formed in the interior wall of the outer housing by manually squeezing the annular portions together. This permits removal of the module for repair or replacement. The annular portions of the snap ring are formed with angled slots that receive projections that extend from the cover of the module to produce a camming movement that uniformly retracts the snap ring out of the annular groove to more readily permit removal of the module.

A device for reducing damage to an electric vehicle powered by a trailing cable, the device including an electric sensor for determining the mobile equipment's position relative to a hazard, and an electric controller responsive to the electrical means for operating a motor to change the operation of the electric vehicle to reduce the likelihood of adverse effects to the trailing cable if the electric vehicle's position is near the hazard.

The universal clipping retainer for engaging a bundle of tubular elements to a frame rail flange of a vehicle comprises first and second sections. The first section comprises structure to which a tubular bundle is engaged by means of a cable tie strap member, the strap member extending through openings in the section, extending around the bundle and engaging to itself. The second section is a clip engaged to one end of the first section, the clip comprising a plurality of fingers biased toward a centerline of the clip for engaging a frame rail flange therebetween, each of the fingers having barbs on a flange engaging surface thereof, with the barbs pointing away from free ends of the fingers.
