Patent number: 6779557Abstract: A multi-port rotary disc valve comprising a stator with a plurality of fluid flow ports and a rotary distributor with a plurality of channels arranged in a channel pattern. The channels are adapted to connect the ports between them and/or to the environment in a plurality of predetermined combinations, each combination being associated with an angular position of the rotary distributor with respect to the stator. The succession of combinations performed during a full or partial unidirectional turn of the rotary distributor constitute a predetermined sequence. The rotary distributor comprises a rotor and a mask mounted movably thereon, the rotor and the mask accommodating the plurality of channels. The mask is adapted to change the channel pattern by changing its position with respect to the rotor, thereby enabling the rotary disc valve to perform different predetermined sequences corresponding to different positions of the mask.Type: GrantFiled: August 22, 2002Date of Patent: August 24, 2004Assignee: Mego Afek Industrial Measuring InstrumentsInventor: Aharon Weiss

Publication number: 20040144432Abstract: The tile flow regulator disclosed is used for regulating the level of water in the fields of an agricultural operation according to seasonal needs by a mechanism for adjusting the outflow of water from the tile line. The regulator includes a housing through which water from the tile line is directed and in which a partition with at least one aperture is positioned. At least one vertically movable gate is associated each aperture and with a motor, an electric cylinder, and at least one actuator bar such that, upon actuation of the motor, the gate moves to either open or close the aperture. If two apertures are included, the regulator can be fully open (both apertures open), fully closed (both apertures closed), or partially open (bottom aperture open, top one closed) to achieve the desired moisture level. Dates on which the gates will be moved can be pre-selected by remote signaling.Type: ApplicationFiled: January 16, 2004Publication date: July 29, 2004Inventors: Charlie J. Schafer, Leo E. Beebout, William Littler

Patent number: 6763845Abstract: An automatic water freeze prevention device having a first valve, second valve and third valve that cooperate to fill or drain a water utilization device according to pre-selected temperature conditions. These three valves are driven to their respective open/closed positions by an electrical power sending device that is, in turn, actuated by a temperature setting device that is associated with a temperature sensing device.Type: GrantFiled: September 9, 2002Date of Patent: July 20, 2004Inventor: Javier J.

Patent number: 6755204Abstract: A land (56) on an index member (32) disposed in the interior chamber of a manifold (38) is aligned with an actuating member (34) and thereby holds open a check valve (36) through which fluid flows into the manifold's interior chamber, through a control valve (12), and out a manifold outlet (74). At the same time, another actuating pin (42) is so aligned with a recess (58) in the indexing member (32) as to permit another check valve (44) to prevent flow through itself into the manifold chamber. When the control valve is closed, flow stops, and pressure builds up in the manifold chamber. The index member (32) is accordingly driven against the force of a bias spring (48) to a lower position, in which a lower cam-follower surface (82) engages a lower cam surface (84). That engagement rotates the index member to a position in which it permits pressure to be communicated through both check valves (36 and 44) into the manifold chamber.Type: GrantFiled: March 4, 2002Date of Patent: June 29, 2004Assignee: Arichell Technologies, Inc.Inventors: Kay Herbert, Natan E. Parsons, Fatih Guler

Patent number: 6732760Abstract: This device comprises a body (2) having outlets (8), and a bonnet (3) housing a rotor (6) being submitted to the action of the inflowing fluid and being connected to a reducing gear (15) activating the closing device. This device is characterized in that the opening of the outlets (8) is carried out with respective angularly sliding shutters (9) being turned by means successively shifting them in opposite directions to thus respectively obtain the opening and closing of the outlets (8). The means shifting the shutters (9) are made up by studs (12, 13 and 14) being provided on the lower surface of the rotary intermediary plate (4) being solid with the reducing gear (15).Type: GrantFiled: March 4, 2003Date of Patent: May 11, 2004Assignee: Sacopa, S.A.U.Inventors: Rafael Ruiz Mellado, Emilio Serrano Sanchez

Patent number: 6715508Abstract: The tile flow regulator disclosed is used for regulating the level of water in the fields of an agricultural operation according to seasonal needs by a mechanism for adjusting the outflow of water from the tile line. The regulator includes a housing through which water from the tile line is directed and in which a partition with at least one aperture is positioned. At least one vertically movable gate is associated each aperture and with a motor and gear assembly such that, upon actuation of the motor by a 12-month calendar, said gate(s) move to either open or close the aperture. If two apertures are included, the regulator can be fully open (both apertures open), fully closed (both apertures closed), or partially open (bottom aperture open, top one closed) to achieve the desired moisture level.Type: GrantFiled: June 6, 2002Date of Patent: April 6, 2004Assignee: Agri Drain CorporationInventors: Charlie J.

Patent number: RE42633Abstract: A spool valve is provided with a stem portion that defines a fluid passageway formed by either (a) a single central support having a non-cylindrical curved surface shaped hydrodynamically, or (b) only a pair of sidewalls with, preferably, interior surfaces that are also shaped hydrodynamically. These stem passageways, which are designed to facilitate the flow of high-speed/high-pressure fluids controlled by the valve, are maintained in a predetermined orientation relative to the ports of the valve cylinders by a mechanism preferably including (a) a cam-following roller supported in a tang fixed to each spool and (b) a two-element cam that captures the roller within two of the parallel sides of a cam-track groove formed on the respective interior surfaces of each cam element.Type: GrantFiled: September 14, 2004Date of Patent: August 23, 2011Assignee: Torvec, Inc.Inventors: Vernon E.
