Abstract: A water jet assembly includes a faceplate with at least one opening, a housing constructed to cooperate with the faceplate, and a mover disposed within a chamber of the housing. The mover is configured to move between a first position adjacent the at least one opening of the face plate and a second position offset from the faceplate to provide a variable volume within the chamber. The water jet assembly also includes an exciter connected to the housing and configured to transition the mover between the first position and the second position to increase and decrease the volume to move fluid into and out of the chamber via the at least one opening.

Abstract: A device and method for producing pulsating waves of energy for the massaging effect normally associated with high pressure jet systems in whirlpools, pedicure spas, bathtubs and other medical and non-medical devices. The jet assembly includes no external pipes and unlike “pipeless” jet assembly systems in use today, does not require disassembly or circulation of chemical cleaning agents to maintain a sanitary condition of the jet assembly.

Abstract: A fuel rail assembly for an internal combustion engine including an elongated rail having a longitudinal inlet passage and a longitudinal outlet passage. The upstream end of the inlet passage is connected to a fuel supply line while the downstream end of the inlet passage is connected through a pressure regulator to the upstream end of the outlet passage. A return fuel line is connected to the downstream end of the outlet passage. A plurality of injector bores communicate with the inlet passage and extend to the exterior of the rail and each injector bore receives one end of a fuel injector, while the opposite end of each injector is sealed within a bore in a runner of an intake manifold. The injectors are mounted in a manner to provide limited tilt to facilitate assembly with the bores in the fuel rail and the manifold reservoir.

Abstract: An improved intake manifold and plenum construction for an electronic fuel injected engine. The manifold includes a plurality of parallel runners, with each runner having a lower end communicating through a port in the cylinder head with a cylinder of the engine, and an open upper end. A fuel injector is mounted in each runner for injecting fuel into the runner. A plenum is mounted on the manifold and includes an upper wall and a lower wall which is spaced from the upper wall to define an air chamber, The upper ends of the runners communicate with the chamber, so that air is drawn from the chamber through the runners to the cylinders.

Abstract: A dual bore throttle body assembly for a marine engine. The assembly includes a body having a pair of side-by-side bores, each of which is adapted to be enclosed by a flat throttle valve. A separate shaft is connected to each throttle valve and a throttle cable is connected to the shafts through a progressive linkage. The linkage is constructed such that only one of the valves is initially opened, and when that valve is approximately 50 percent open, the second valve is then opened. The speed of opening of the second valve is greater than that of the first valve so that both valves will reach the full opened position at the same instant. Each shaft is provided with a longitudinal slot which receives the respective throttle valve, and the valves are secured within the slots by mechanical fasteners such as screws.

Abstract: A vapor separating unit for a fuel system and having particular application to a fuel system for a marine engine. The vapor separating unit includes a closed tank having a fuel inlet through which fuel is fed to the tank by a diaphragm pump. The liquid level in the tank is controlled by a float-operated valve. An electric pump is located within the vapor separating tank and has an inlet disposed in the tank and an outlet connected to a fuel rail assembly of the engine. Excess fuel from the fuel rail assembly is conducted back to the upper end of the vapor separator tank. A vapor venting mechanism is incorporated in the tank to vent vapor from the tank.
