A sprinkler assembly includes a body defining an inlet, an outlet, and a fluid passage extending along a longitudinal axis between the inlet and the outlet. A guide pin aperture is defined by at least one of the body or a bushing coupled to the body. The sprinkler assembly further includes a deflector slidably coupled to the body. The deflector includes a deflector body coupled to a guide pin. The guide pin includes a shaft portion extending through the guide pin aperture and a shoulder that is wider than the shaft portion and configured to engage at least one of the body or the bushing to limit movement of the deflector body away from the body.

A spray gun for a high-pressure cleaning appliance is provided, with a gun casing, in which is arranged a valve, which has a through duct which extends from a valve inlet to a valve outlet, and has a closure body which, in a closed position, bears in a fluid-tight manner against a valve seat and which is adapted to be moved, with the aid of a hand lever mechanically coupled to the closure body, into an open position spaced apart from the valve seat, and with an electric apparatus which has an electric display device and at least one battery. The electric apparatus has an electric casing which is sealed against sprayed water and forms a sub-unit adapted to be handled independently, wherein all of the current-carrying components of the spray gun are arranged in the electric casing and are separated galvanically from the remaining components of the spray gun.

The invention relates to a dosing system (1) for dosing a dosing material. The dosing system (1) has a housing (11), comprising a nozzle (70) and a supply channel (62) for dosing material, and a discharge element (80) movably mounted in the housing (11) and an actuator unit (10) coupled to the discharge element. The actuator unit (10) comprises an actuator (12) having a membrane (13) which can be pressurized by means of a pressure medium in order to move the discharge element (80) in a discharge direction (RA). The discharge element (80) is formed separately and, for coupling to the actuator unit (10), is pressed by means of a force acting on the discharge element (80) against a side surface (19) of the membrane (13) pointing in the direction of the discharge element (80). Furthermore, the invention relates to a method for controlling a dosing system (1).

Jetting devices and methods for dispensing a fluid material from a fluid supply. A jetting device includes a fluid module configured to be coupled with the fluid supply and to dispense the fluid material. The fluid module includes a valve seat and a valve element configured to move relative to the valve seat over a stroke length, and a valve stop configured to position the valve element relative to the valve seat for determining the stroke length. The jetting device further includes a drive module configured to actuate the fluid module and includes a drive pin configured to move the valve element toward the valve seat. The drive pin is configured to be rotated to cause rotation of the valve stop for adjustment of the stroke length. The drive pin may be rotated by a rotation device comprising a motor.

A valve for use in conjunction with an application device having a valve housing and a valve spindle which bears a sealing element at a first free end outside the valve housing and, within the valve housing, is mounted displaceably between a closed position and a release position. The valve spindle includes at least one first piston element and at least one second piston element, wherein the first piston element is guided in a first piston space and the second piston element is guided in a second piston space, said piston spaces being bounded by the valve housing. A pressure fluid can be supplied in each case to the first piston space and to the second piston space in such a manner that a force acting in the same direction is exerted on the first piston element and on the second piston element.

A multi-positional valve is used to control the destination of gas flows from multiple gas sources. In one valve position the gases flow to an isolated vacuum system where the flow rate and mixture can be adjusted prior to introduction into a sample vacuum chamber. In another valve position the pre-mixed gases flow from the isolated vacuum chamber and through a needle into the sample vacuum chamber.

A blow gun includes a body with first and second paths, a trigger, a control unit, a first spring, a second spring and a first pin. The control unit includes a control member, a bar, a seal ring, an end member, a collar and a fastening member. The control member is received in the first room and has a slot located corresponding to the first hole. The end member is connected to the control member and the seal ring is mounted to the end member to seal the communication between the first and second paths. The first spring is biased between body and the control unit. The second spring is biased between the body and the trigger. The first pin extends through the first hole and is movable in the slot of the control member. The two springs share the force applied thereto to have a long service life.

A hydraulic spray nozzle for an agricultural implement includes at least one of a bleed valve and an annular valve. The bleed valve is configured to control flow of a bleed portion of the liquid provided to the nozzle for spraying. The bleed portion can be routed back to a supply tank for later use. The bleed valve can be an annular valve. A spray valve within the nozzle can also be an annular valve.
