Abstract: The present invention provides an irrigation control valve for converting water supplied to the irrigation control valve at a constant, low-volume flow rate into a pulsed, high-volume flow rate discharge. The irrigation control valve includes a control valve body having an inlet coupled to the water supply tube, an accumulation chamber, a mist port and a mist valve assembly for intermittently discharging the water from the accumulation chamber out of the mist port. The irrigation control valve further includes a pressure relief valve assembly operably coupled to the water supply tube for relieving the pressure within the accumulation chamber when the irrigation control valve is not in use.

Abstract: A port throttle valve and an intake system incorporating the valve is disclosed. The valve is disposed between one of two intake runners delivering air to the intake port of an engine cylinder and includes a base member having an opening for delivery of air therethrough. The base includes a track in which is slidingly disposed, two adjacent valve plates each having an opening for registry with the opening in the base member to allow for the passage of air. When moved, in opposite longitudinal directions, the edges of the openings in the valve members move towards one another to terminate registry of the openings with the opening in the valve body.

Abstract: An EGR transfer assembly includes a tubular conduit having a first end in communication with a source of exhaust gas and a second end located in an oversized opening in the engine intake manifold. A seal carrier configured as a cylindrical sleeve having a flanged portion at one end, is received over the second end of the conduit such that the cylindrical portion is inserted into the opening in circumjacent relationship to the conduit to define an insulating space therebetween. The flanged portion of the carrier limits the entry of the cylindrical sleeve into the manifold by seating against the manifold. Seals are disposed between the sleeve and the conduit and between the flange and the manifold to limit the leakage of air through the manifold opening. A spring member is seated between the seal carrier and a stop member and acts to seat the flanged portion against the manifold.

Abstract: The present invention provides an irrigation control valve for use in an irrigation system having a liquid supply tube providing liquid to be emitted from the irrigation control valve. The irrigation control valve includes a control valve body having an inlet coupled to the liquid supply tube, a drip port for providing drip irrigation from the irrigation control valve and a mist port for providing mist irrigation from the irrigation control valve. The irrigation control valve further includes a displaceable structure disposed within the control valve body for directing liquid to the drip port or the mist port in response to a control signal.

Abstract: A one-piece integrally molded intake manifold is for an engine having opposed cylinders. The intake manifold comprises a plurality of runners each of which is coiled about a runner center. The runners are arranged side-by-side so that the runner centers lie on a common manifold axis. Adjacent ones of the runners are oppositely curved and interdigitated with one another so that a generally cylindrical plenum is defined by the space around which the runners are coiled. Each of the runners includes a runner inlet and upper and side runner surfaces adjoining the runner inlet. The portion of the upper and side runner surfaces adjoining the runner inlet are outwardly flared so that the cross section of the runner decreases from the runner inlet into the runner. The intersections between the upper and side runner surfaces are rounded. Air in the plenum can flow through the flared runner inlets into the runners.

Abstract: An integrated induction system for providing fluids to the cylinders in an engine comprises a casing adapted for mounting on the engine. The casing has an air inlet and a plurality of fluid outlets. A plurality of air tubes are disposed within the casing so that air entering the air inlet flows through the air tubes and respective fluid outlets to the cylinders. A fuel injection assembly is mounted within the casing to inject fuel into the air exiting the air tubes adjacent each of the fluid outlets causing a mixture of air and fuel to enter the respective cylinders.

The distribution mountings have passages to allow communication between air and fuel contained within the casing and the cylinders, and to allow communication between a supplemental fluid source and the cylinders.

Abstract: A fuel injection assembly for an engine comprises a fuel injector having an injector outlet and a nozzle having a nozzle passage with a nozzle inlet and outlet. The nozzle passage includes a converging portion adjacent the nozzle inlet and a diverging portion adjacent the nozzle outlet. The fuel injection assembly further comprises a nozzle support for attaching the nozzle to the fuel injector so that the injector outlet registers with the nozzle passage adjacent the nozzle inlet enabling injection of fuel from the fuel injector into the nozzle passage. The nozzle has a nozzle port adjacent the nozzle inlet enabling the establishment of an air flow which enters the nozzle passage adjacent the nozzle inlet and exits the nozzle passage through the nozzle outlet. At least a portion of the air flow in the nozzle passage is sonic enabling the fuel injected into the nozzle passage to mix with the sonic air flow and be carried by it through the nozzle passage and the nozzle outlet.
