Abstract: An apparatus for applying a fluid to a moving carrier strip includes a distributor and a plurality of individual flow channels which together form a multi-jet nozzle. The individual flow channels in the form of capillary tubes are arranged at right angles to the distributor axis at equal distances along a longitudinal line parallel to the distributor axis. The capillary tubes protrude into an internal chamber of the distributor and the capillary tube located at each end of the longitudinal line protrudes further into the interior of the distributor than the other capillary tubes.

Abstract: A nozzle is disclosed which has a cylindrical nozzle main body. A nozzle tip of the nozzle comprises a plurality of members formed by dividing an approximately cylindrical member in the axial direction thereof and is accommodated in the interior of the nozzle main body. A spring is provided between a spring receiving section of the nozzle tip and a wall positioned on a forward side of the nozzle main body. At least one of a peripheral surface of a discharge section of the nozzle tip and an inner surface of a tip engaging opening of the nozzle main body is tapered. A self-cleaning operation is performed when the atomization pressure is reduced, because the spring urges the nozzle tip toward a rearward side of the nozzle main body.

Abstract: A fluid jetting pipe for discharging fluid jets. Variable outlet members are disposed at an outlet end of the jetting pipe such that the outlet opening area through which the fluid jets are allowed to discharge from the jetting pipe is fully opened in a normal state and can be narrowed down on demand.

A non-rotatable shaft supports at one end thereof a substantially hollow distributor for rotation thereon downstream of the outlet. The other end of the shaft is fixedly mounted in the first inner housing, and the hollow distributor includes an interior chamber enclosing a brake assembly for retarding the rotation of the distributor.

Abstract: A fuel injector includes a housing (2) having fuel upstream inlet and downstream discharge end portions. The discharge end portion is adapted to adjustably receive a valve assembly (9). The valve assembly, in turn, includes a valve poppet (18), seat (17) and biasing primary compression spring (21) arrangement which is adjustable prior to the assembly's insertion into the injector housing. The inlet end portion of the housing includes a magnetic coil (25) and an armature (29) which forms a working gap (33) with the housing. The armature is attached to an actuator (34) which engages the valve assembly. A secondary compression spring (37) is confined between the armature and an upstream fuel inlet member (39) adjustably mounted to the housing. A first or preload adjustment is to the compression of the primary spring in the valve assembly, which is then inserted into the housing.

Abstract: A bubbler includes two molded plastic parts, a main body portion with an internally threaded upper chamber terminating in a valve seat, and a hollow cap with a downwardly extending externally threaded valve stem for engagement with the internally threaded upper chamber of the body portion. Elongated channels extend from the open upper end of the body portion to a position adjacent the valve seat. When the cap is threaded onto the body portion with the end of the valve stem spaced from the valve seat, water flows from the lower chamber of the body portion past the valve seat and upwardly through the channels into the hollow part of the cap and then out through a space between the skirt on the cap and the body portion. When the cap is threaded downwardly to cause the valve stem to engage the valve seat, the bubbler is closed and no water flow takes place through it.

Abstract: An apparatus for cleaning surfaces by means of a jet of cleaning liquid comprises a sluicing pipe with a housing provided with a tiltably arranged nozzle assembly. The latter is adapted to perform oscillations by means of a hydraulic motor mounted in the housing and driven by the cleaning liquid flowing to the nozzle assembly. The nozzle assembly is located within the housing and comprises at its front end a contact surface, by means of which it is capable of tilting on the bearing surface provided with a discharge opening on a discharge member located at the outlet of the housing. The discharge member comprises a central flow channel for the cleaning liquid, and the discharge opening has a sectional area greater than the hole area of the nozzle assembly. As a result the reliability is increased, as the apparatus is self-adjusting with regard to the wear caused by the movement of the nozzle assembly. The apparatus is furthermore easily assembled.

Abstract: A spray orifice particularly adapted for discharging a mixture of an atomized release agent entrained within a gas stream for coating a surface of a forming die. The orifice includes a body section having an internal cavity terminating in a ball-shaped cavity portion adjacent its outlet end. The outside surface of the body adjacent the outlet end has a shape complementary with the inside surface to provide a relatively uniform wall thickness. A laterally extending slot is cut into the end and has a maximum width at its center and tapers to a minimum width at its lateral ends. Such configuration reduces the likelihood of finely atomized liquids dispersed in the pressurized gas stream from recombining to form larger size droplets. The included angle of discharge from the slot is adjustable through a rotatable adjustment cap having diametrically opposite cam surfaces which selectively cover side portions of the slot. A lock nut is used to maintain the adjustment cap in a desired set position.

Abstract: In an injection valve for fuel-injection systems for internal combustion engines, the closure member opens in the direction towards the combustion chamber. It has an outer surface which widens towards the combustion chamber. Above the closure member, a swirl chamber is provided in the housing of the injection valve, fuel continuously rotating in said swirl chamber as a result of a continuously open return-flow connection to a valve outlet.

Abstract: An electromagnetically actuatable valve which serves as a fuel injection valve for fuel injection systems in internal combustion engines. The valve includes a valve housing as well as a magnetic coil with poles serving as the core, with which an armature cooperates, which is connected to a valve element the sealing element of which cooperates with a valve seat in a valve seat body. The valve element protrudes without contact through a throttle bore in the valve seat body with a throttling element and is held in a sealing manner on the valve seat by the armature when the magnetic coil is excited. When the magnetic coil is not excited, the valve element is moved by the pressure forces of the fluid in the opening direction of the valve and is centered by the fluid flow.

The socket is connected with the inner chamber part (2) so that it can be telescopically inserted therein to form a storage position. In dosage dispensing position the socket is extended from the deceleration chamber, pivoted at an angle relative to the longitudinal axis of the chamber and locked in the angle.

Abstract: An adjustable pattern powder spray nozzle assembly comprising a nozzle body having an axial powder flow passage extending therethrough and a pair of rotatable adjacent shafts extending across the powder flow passage. The shafts are in contact with each other substantially along their length and each has a slot formed in the periphery thereof. The slots are oppositely positioned so as to define a powder flow opening therebetween. The shafts are interconnected by gears at the ends thereof so that they are rotatable in unison to vary the configuration of the opening and thereby, the pattern of powder sprayed from the nozzle assembly.

Abstract: A filling machine for packaging divided solid material having a conduit for feeding the material under pressure into a packaging container, wherein an elastic liner is disposed in and extends along a part of the length of the conduit, has its opposite ends secured to the conduit, and cooperates with the inner surface of the conduit to form a cavity. The conduit is formed with a vent opening to the cavity to permit outward expansion of the liner when material is flowing through the conduit and inward contraction of the liner when there is no flow through the conduit, thereby flexing the liner to crack and break off material adhering to the inner surface of the liner.
