A spray nozzle chip is presented having: a first layer provided with a first layer orifice, a mechanically flexible nozzle layer provided with a nozzle orifice, the spray nozzle chip having a valve functionality obtained by movement of the nozzle layer relative to the first layer due to pressure changes, wherein the nozzle orifice is closed when the nozzle layer is in a default non-pressurised state and wherein the nozzle orifice is opened and set in fluid communication with the first layer orifice when the nozzle layer is deformed due to pressure during a spraying operation, and wherein the spray nozzle chip further has a sealing layer configured to rupture when the nozzle layer is deformed due to applied pressure during a spraying operation.

The invention relates to a device for injecting a fluid, in particular a cryogenic fluid, the device comprising a fluid feed head and a fluid dispenser body, detachably mounted on said feed head, said feed head comprising a groove for circulating the fluid fed to said body, said groove being closed when the body is mounted on the feed head and said groove being open when the feed head and the body are detached from one another.

In one general aspect, a flow control valve includes: a housing including a tubular wall surrounding an interior passage, and a flow control section in which the tubular wall includes a conical inner wall surface; a protrusion disposed on an exterior surface of the tubular wall at the flow control section; a sealing member disposed in the housing and configured to be selectively moved to a sealing position in which the sealing member engages the conical inner wall surface to restrict flow of a fluid through the interior passage; and a recess disposed the conical inner wall surface and configured to allow the fluid to flow past the sealing member through the recess when the sealing member is in the sealing position, wherein the recess and the protrusion are radially aligned on the tubular wall.

A shower jet generating device for a sanitary shower head has a jet disk that delimits a fluid chamber on the outlet side and has at least one jet disk opening. A fluid outlet element is disposed on the at least one jet disk opening and is movable in an axial main direction component, which element includes a movable valve body having a fluid outlet opening issuing from the fluid chamber. The fluid outlet opening is unblocked in an unblocking position of the fluid outlet element and is blocked in a blocking position of the fluid outlet element in response to a fluid pressure in the fluid chamber. The movable valve body cooperates with an unmovable valve seat which unblocks the fluid outlet opening in the unblocking position of the fluid outlet element and blocks it in a blocking position of the fluid outlet element.

A sprinkler includes a pop-up deflector plate that is engageable with a brake assembly in an extended position. A brake module is secured to a sprinkler body and includes a rotatable connector coupled with the brake assembly. The pop-up deflector plate is disposed adjacent the nozzle and engages the rotatable connector in the extended position.

A control structure capable of adjusting water volume and controlling water supply contains: a body, a fixer, a valve stem, an adjuster, and a controller. The body includes a water outflow segment for connecting with a watering tool, an accommodation groove for accommodating the fixer and the valve stem. The fixer includes a flexible retaining rib, and the valve stem includes an inlet communicating with the water outflow segment, a fixing rib, an opening communicating with the inlet, and a guiding column. The guiding column has a seal ring. The fixing rib retains with the flexible retaining rib so as to limit a rotation of the adjuster along the body. The adjuster includes a threaded orifice screwing with a screwing section of the controller, an inflow aperture fitting with the guiding column, and a shoulder formed beside the inflow aperture. The controller is coupled with a water supply pipe.

In a cleaning nozzle unit including an inner liquid passage guiding a cleaning solution, an inner air passage feeding air to an outlet of the inner liquid passage, and an injection port that mixes the cleaning solution guided by the inner liquid passage and the air fed by the inner air passage and injects a mixture of the cleaning solution and the air to a surface of an object, a plurality of the injection ports are provided, are disposed at predetermined intervals and inject the mixtures in directions such that the mixtures hits each other in the surface at a substantially predetermined angle in a front view of the surface.

A washing device includes a nozzle portion reciprocally movable between an accommodating position and a washing position. The washing device is configured to wash a surface of an external washing target by supplying fluid to the nozzle portion, moving the nozzle portion from the accommodating position to the washing position using pressure of the fluid, and spraying the fluid from a spray port of the nozzle portion onto the surface of the washing target. The nozzle portion is configured to reciprocate along one of a curved path and a bent path between the accommodating position and the washing position.

Described is a nozzle for spraying substances, in particular dispersions, emulsions or suspensions.

A tank cleaning nozzle (2) configured to be mounted on a tank (6), wherein said tank cleaning nozzle (2) comprises an inlet (42), an outlet (26) and an interior space (54) being in fluid communication with the inlet (42) and the outlet (26), The tank cleaning nozzle (2) is configured to receive a pressurized liquid (36) through the inlet (42) and inject the liquid (36) through the outlet (26) into the tank (6), The tank cleaning nozzle (2) comprises a moveably arranged closing structure (34, 52) configured to close the outlet (26). The closing structure (34, 52) is arranged and configured to be moved into a position, in which the outlet (26) is provided with a free passage, through which the liquid (36) leaving the outlet (26) is injected into the interior space (54) without colliding with the closing structure (34, 52).
