8297314 Solenoid actuated pilot valve for irrigation system valve October 30, 2012
A solenoid actuated pilot valve includes a pilot valve housing defining a pilot valve chamber and a solenoid. The solenoid includes and end cap connected to the pilot valve housing, a reciprocable plunger, and a piston having a shaft with a first end connected to and end of the plung
8272578 Sprinkler with adjustable arc and adjustable radius September 25, 2012
A sprinkler includes a stream nozzle with a plurality of circumferentially spaced, radially extending stream forming ports. A non-rotating arc adjustment sleeve is mounted for axial movement relative to the stream nozzle to selectively block the stream forming ports to vary an arc of
8220723 Gear driven sprinkler with top turbine July 17, 2012
A sprinkler comprises a nozzle, a turbine and a gear train reduction. The gear train reduction has an output stage that is coupled to the nozzle. The turbine is located between the nozzle and the gear train reduction and is coupled to an input stage of the gear train reduction.
7677469 Sprinkler with reversing planetary gear drive March 16, 2010
A sprinkler for irrigating turf and/or landscaping includes a turbine and a nozzle. A planetary gear drive and a reversing mechanism rotatably coupling the turbine and the nozzle. The planetary gear drive includes at least a portion of the reversing mechanism.
7665713 Sleeve valve for residential and commercial irrigation systems February 23, 2010
A sleeve valve includes a rigid mandrel with a plurality of openings and a generally cylindrical elastomeric sleeve that surrounds the mandrel. A generally cylindrical rigid sleeve valve housing surrounds the elastomeric sleeve and defines a control chamber between the elastomeric sl
7503346 Solenoid actuated pilot valve for irrigation system valve March 17, 2009
A solenoid actuated pilot valve includes a pilot valve housing defining a pilot valve chamber and a solenoid. The solenoid includes and end cap connected to the pilot valve housing, a reciprocable plunger, and a piston having a shaft with a first end connected to and end of the plung
7040553 Rotor type sprinkler with reversing mechanism including sliding clutch and driven bevel gears May 9, 2006
A Pelton type turbine is mounted in a riser of a pop-up sprinkler for rotation about a horizontal axis and drives a central bevel pinion gear through a gear train reduction. Upper and lower bevel gears supported on a vertical drive shaft are simultaneously driven in opposite directions
6957782 Irrigation spray nozzle with two-piece color identifier and radially shaped orifice October 25, 2005
An exterior portion of the nozzle with a top side viewable from above the turf or ground surface mates with a base portion of the nozzle to define a nozzle orifice and a flow path leading to the nozzle orifice. The base portion has at least one projection that extends through an aperture
6848632 Pop-up irrigation sprinkler having bi-level debris strainer with integral riser ratchet mechanis February 1, 2005
A frusto-conical strainer is mounted on the lower end of a pop-up riser for filtering out debris from water entering the lower inlet end of a surrounding outer housing to prevent clogging of the nozzle orifice or damage to mechanical components within a sprinkler. A cylindrical scrubber
6840460 Rotor type sprinkler with insertable drive subassembly including horizontal turbine and reversin January 11, 2005
A sprinkler includes an outer housing having a lower end connectable to a source of pressurized water and a riser that is vertically reciprocable within the outer housing between extended and retracted positions when the source of pressurized water is turned ON and OFF. A nozzle is mount
6817543 Toggle over-center mechanism for shifting the reversing mechanism of an oscillating rotor type s November 16, 2004
A Pelton type turbine is mounted in a riser of a pop-up sprinkler for rotation about a horizontal axis and drives a bevel pinion gear reversing mechanism through a gear train reduction. One end of a yoke is coupled to a clutch and the other end is moved vertically by an over-center mecha
6695223 Adjustable stator for rotor type sprinkler February 24, 2004
An adjustable stator is mounted in the lower end of a pop-up sprinkler riser and includes a vertically extending frame portion and a pair of valve portions that extend horizontally from an upper end of the frame portion. A coil spring is squeezed between a lower end of a drive subass
5375768 Multiple range variable speed turbine December 27, 1994
A sprinkler unit for distributing water from a source over an area of terrain comprises a tubular housing having an inlet connected by a passage to an outlet, a distributor head mounted at the outlet for rotation about an axis for distribution of water via a nozzle, a turbine wheel dispo
