A fuel injector nozzle has a housing defining a blind bore with at least one fuel injection spray orifice defined at a bottom portion of a spray tip and a guide passage defined at a top portion of the bore. An injection chamber of the bore is disposed between the orifice and the guide passage. A fuel injection passage intersects the guide passage. A needle check is slidably disposed in the blind bore for movement between a first position and a second position. In the first position, a seat porti...

A trigger sprayer contains a valve element that vents air from a pump chamber of the sprayer, while priming the pump, to the interior of a liquid container to which the sprayer is attached. In an alternate embodiment, the valve element includes an integral check valve.

A windshield washer system has a nozzle mounted on a vehicle for issuing wash fluid to a windshield and a check valve for a fluid circuit from a supply of wash fluid to the nozzle. The nozzle has a fluid feed tube integrally formed therewith with annular walls defining a washer fluid flow path and a diameter of at least D. The feed tube has an external surface adapted to receive and retain a flexible hose from a supply of wash fluid. A spring shoulder receives a coil compression spring having up...

A machine in accordance with the invention includes a sprinkler gun (3) placed at the end of a hose (1) which is wound onto a drum (2) rotated by a flexible actuator (12) which actuates a rocker arm (13) carrying a finger (15) co-operating with regularly spaced-apart holes situated in a ring (31). The machine includes a computer (18). The machine also includes a sensor (30) for sensing angular displacement of the drum and situated in the proximity of the ring (31). The machine also includes a pr...

A spray coating device includes a ring (14) surrounding a spray device (4) radially spaced and supporting at least one electrode (28). Gas flowing across the ring (14) and electrode transmits electrical charges from the electrodes to particles of atomized coating material, downstream from a spray head (6) of the spray device (4). The electrical charging of the coating material is considerably increased thereby.

A mounting and placement system for the periodic and manual placement of one or more sprinkler heads around a yard or other area that needs periodic watering, said sprinkler heads being advantageously made in accordance with conventional designs. A shank or spike depends from the body of such water sprinklers, said spike being downwardly tapered to a point. A plurality of generally tubular anchor members are sized and configured to telescopically receive the spike of the sprinkler. The lower end...

An automotive fluids dispensing and blending system wherein a customer may select various fuel additives such as octane enhancers, fuel injector cleaners, varnish dissolvers, compounds to free-up piston rings, etc., all choices of which may be automatically blended with the selected fuel as the fuel is being dispensed normally into the vehicle fuel tank. The system also allows the customer to select and dispense various engine oils and oil additives, antifreeze solutions, windshield washer fluid...

The invention relates to an injection valve for internal combustion engine fuel injection systems. The valve is designed to inject fuel into the intake manifold. The valve comprises a valve housing containing a core, with which an armature cooperates. A nozzle body with a valve seat is connected to the valve housing. A sealing seat of a valve needle guided in the nozzle body cooperates with the valve seat. The valve needle is guided by first and second guide parts in a guide bore of the nozzle b...

The gun grip (18) and the gun barrel (2) are two bodies that are detachably connected with each other. The fluid line (26) is a stiff tube with two tubular shanks (27, 28) which at said angle extend obliquely to each other. The one tubular shank (28) is removably installed in a channel (25) of the gun grip (18), the other tubular shank (27) in a first channel (10) of the gun barrel (2), each from sides of the gun grip (18) and the gun barrel (2) that border on each other.

A combined fence and irrigation system is formed by a plurality of generally vertical spaced posts and a plurality of generally horizontal connecting rails. A countersunk circular aperture is formed through each face of the rectangular posts at a predetermined vertical level. Each of the posts terminates in a ground insertion spike and is of a tubular construction to allow fluid passage. An end face of each of the rails is provided with a central countersunk circular aperture. The countersunk ap...
