Abstract: A nozzle for water jet equipment and a method of use thereof. The nozzle has a body including a base with a shaft extending outwardly therefrom. The shaft is inserted through a bore of a sleeve that rotatable about the shaft. The base and shaft define a bore therein. At least one opening is defined in the shaft and one or more grooves are milled into the shaft's exterior surface. Each opening places the body's bore in fluid communication with one of the grooves and the sleeve's bore. Water flowing through the body's bore will flow through each opening, into the associated groove and into a space between the shaft and sleeve. The grooves create turbulence in water in this space and thereby reduce leakage from the nozzle. The shaft terminates in a conical section usable as a battering ram to break up blockages in pipes during cleaning operations.

Abstract: A trigger sprayer has a housing, a piston bore within the housing, and a piston reciprocally mounted within the piston bore. The housing further includes a flow passage through which liquid passes from a passage inlet to a passage outlet. An actuator is operable to reciprocate the piston within the piston bore between a vacuum stroke creating reduced pressure in the piston bore and a compression stroke creating increased pressure in the piston bore. A valve assembly within the flow passage controls the flow of liquid through the flow passage upon operation of the actuator. The valve assembly further comprises a check valve and a priming valve. The sprayer has a closure for mounting the sprayer to a container. The valve seat for the check valve is in a component formed separately from and operatively connected to the housing.

Abstract: The invention relates to an airless dispenser which is used to dispense low doses of liquid products. The inventive dispenser is characterised in that it consists of: a first part comprising a spray nozzle which is communicated with a network of channels on the wall of an inner truncated-cone-shaped bore, and a second part comprising a deformable container which equipped with a rigid flange for fixing the first part in the aforementioned bore. The outer periphery of the flange comprises an inclined surface which defines a vortex chamber, opposite the above-mentioned network of channels, and which, together with the wall of the first part, forms an internal peripheral outlet groove. The outlet groove is defined radially by a flexible lip forming an inlet valve which is supported by the first or second part.

Abstract: A sprinkler nozzle having a nozzle housing with an inlet for liquid and having a longitudinally extending axis. The nozzle housing, opposite the inlet, is delimited by a surface of revolution with nozzle outlet openings arranged around the axis. In the flow direction opposite the nozzle outlet openings, respective impact faces are arranged for reflecting the liquid that flows out through the nozzle outlet openings. The impact faces are constituted by the ends of respective threads that are secured to the nozzle housing, whereby the impact faces are able to reflect water that flows out of the respective nozzle outlet openings.

Abstract: The guide member (1) for a liquid jet (30) to be deflected allows a liquid (3) after flowing out of a container (2) to be deflected onto a target (5; 7) which is located below the container. The deflecting takes place by means of a shaped material plate (10; 10a, 10b) which is arranged ahead of an outlet opening (20) of the container and which reshapes and further conducts the jet (30) in such a manner that the liquid is conveyed to the target at a lower end (17) of the shaped material plate. At the location ahead of the outlet opening (20), where the liquid jet (30) is incident onto the shaped material plate (10), a first and a second piece of surface (11 and 12 respectively) of the material plate form a mouth region (13) in which the first piece of surface (11) deflects the liquid (3) transversely with respect to the vertical, whereas the second piece of surface (12) is provided as a catcher for squirts. The first piece of surface merges into a channel (14) in which the liquid is guided downwards.
