A valve nozzle assembly including a number of valve nozzles arranged in a predetermined pattern. Each valve nozzle may include at least one coil; and a magnet adapted to be movable between a closed position closing the nozzle and an open position opening the nozzle, wherein a movement of the magnet between the closed and the open position is controllable by a magnetic field from the at least one coil.

A nozzle assembly includes a body, a valve member, and a clamp member maintaining a flow director member against the body. The flow director member is sandwiched between the peripheral wall and the clamp member, and is provided with an outlet path including two distinct guidance channels extending from an upstream end and a common downstream end where is a spray hole. The outlet path creates impingement of the two flow streams flowing in the two channels before entering the spray hole.

A spray assembly for a working machine that includes a fluid storage tank includes a plurality of nozzle assemblies, each of which includes a direct acting valve. The spray assembly also includes a controller that is operatively connected to each of the direct acting valves for controlling the opening and closing of the direct acting valves, and a selector that is operatively connected to the controller. The selector may be employed by an operator of the working machine to selectively operate one or more of the direct acting valves in order to provide a desired spray pattern of fluid from the fluid storage tank.

A high-pressure valve for a spray nozzle. The high-pressure valve includes a valve inlet, a valve outlet to which the spray nozzle is attachable, a fluid connection which connects the valve inlet to the valve outlet, a movable piston, a tappet which is arranged in the fluid connection, and a flushing apparatus which flushes the high-pressure valve and/or the spray nozzle with a flushing liquid. The tappet moves between a closed position and an open position via the movable piston. A spray liquid reaches the valve outlet and/or the spray nozzle from the valve inlet via the fluid connection when the tappet is in the open position.

A handheld sink sprayer with single-handed metering and discharge mode adjustment. A body includes a handle portion, and a nozzle portion extending from the handle portion. A metering valve is carried in the body, a finger-engageable actuator is carried by the body and is coupled to the metering valve to move the metering valve, and a nozzle is carried by the body nozzle portion. A discharge mode valve is carried by the body nozzle portion. A thumb-engageable actuator is carried by the body nozzle portion and is coupled to the discharge mode valve to move the discharge mode valve between different discharge modes of operation.

A shower control valve with a reasonable arrangement includes a main body, a control member and a holding member. The main body includes a water inlet channel and a water outlet channel. The control member is movably arranged at one end of the main body and used to control on-off between the water inlet channel and the water outlet channel. The holding member includes a connecting part fixedly connected to the other end of the main body, and a hooking part for hooking a shower head. The connecting part and the hooking part are staggered along the radial direction of the main body to form a give-way space, which prevents interference with other parts during the plugging and unplugging process of the shower, and provides a simple structure and strong practicability.

A needle for a jet device includes a needle body and a tapered part arranged at the end of the needle body, in which the needle body is circumferentially provided with supporting bodies, so that when the needle is assembled in a nozzle of the jet device, the outer surfaces of the supporting bodies are coordinated with an inner chamber of the nozzle to limit the position of the needle body and form fluid channels among the supporting bodies, thereby to effectively prevent the needle from deviating from the spout of the nozzle or from radially swinging.

A sprinkler head includes a sprinkler body, a nozzle positioned within the sprinkler body, a fixed gear coupled with the sprinkler body, a wobbler cage supported on the sprinkler body, and a water deflector plate coupled with the wobbler cage and disposed downstream of the nozzle. A brake assembly is coupled with the water deflector plate for slowing a rotating and wobbling motion of the wobbler cage and the water deflector plate. The brake assembly includes a shaft extending through the water deflector plate and a brake gear disposed at an end of the shaft, where the brake gear is engageable with the fixed gear. Among other advantages, the design eliminates the use of large fixed strut framework that creates dry shadows in the water pattern.

A valve injector (10) comprising: a body (12) defining a fluid conduit (14), the fluid conduit (14) accommodating first, second and third checks (16, 18, 20), the first check (16) being disposed within the fluid conduit (14) towards a first end (10a) of the injector (10), the second check (18) being disposed towards a second end (10b) of the injector (10), distally from the first end (10a), and the third check (20) being located between said first and second check (16, 18).

A water-saving sheet and a water-saving device having the same is provided. The water-saving sheet includes a sheet body including a central assembling base and a plurality of through holes arranged around the central assembling base. A circumference of the sheet body has an engaging flange structure for being positionably engaged with an inner wall of a tube. An elastic ring is annularly arranged on the central assembling base. The elastic ring and the central assembling base form at least one first passage therebetween, the elastic ring and each said through hole form a second passage therebetween. The water-saving device includes one said water-saving sheet and a barrel member. An inner wall of the barrel member has a shoulder portion engageable with the engaging flange structure to restrict the sheet body from moving toward and out from the inlet end.
