A water fountain apparatus having a controller with an input panel and running a computer application program having a communication protocol where the controller is communicatively coupled to a submersible assembly. The submersible assembly further includes a servo controller electrically coupled to the controller and being configured to transmit and receive control and power signals. The servo controller is further electrically coupled to a servo or stepper motor, operable to receive control signals from the servo controller to cause it to step clockwise or counterclockwise in steps or increments. The servo motor is coupled to a ball within a ball valve assembly via a servo shaft. The ball valve is operable to open a conduit from a manifold through one of two egress ports, or partially through both egress ports. The manifold is coupled to a pump.

An in-car environment purification diffuser includes a spray cover combined with a tank cover and covered on a slot of a water tank. The oscillation space in the water tank is formed with a tubular protrusion of an air flow channel. When the diffuser is dumped, the liquid in the water tank is less likely to seep into the diffuser or the car. The oscillator mounted in the water tank is coated with an acid-and-alkaline-resistant coating. The user can add safe cleaning liquid such as alkaline hydroxide ionized water into the oscillation space and atomize it as deodorization, sterilization, disinfection, etc. for the car's environmental purification. A light-permeable spray cover with an umbrella-shaped panel is to shield the tank cover. The spray cover is like a paper umbrella with a decorative effect. The umbrella-shaped panel with spray effect is decorative and can create a better atmosphere in the car.

A ball valve for controlling the flow of water to a drip hose is provided. The ball valve includes a manifold including a manifold inlet configured to attach to a riser hose, and one or more valves integrated with the manifold. One or more outlet fittings are attached to each valve adjacent to each valve outlet.

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.

Swivel shower including a shower body with a base body, a swivel body including a shower outlet and mounted for swivel movement relative to the base body between a rest position and an operating position, a shower fluid inlet and a fluid flow path from the shower fluid inlet to the shower outlet. A shut-off valve is arranged within the shower body in the fluid flow path between the shower fluid inlet and the shower outlet and blocks the fluid flow path as a function of a swivel position of the swivel body, wherein the fluid flow path is completely blocked in the rest position of the swivel body and is completely unblocked in the operating position of the swivel body.

Swivel shower including a base body, a swivel body including a shower outlet and held on the base body for swivel movement about a swivel axis between a first swivel body end position, constituting a rest position, and a second swivel body end position, constituting an operating position, a shower fluid inlet for supplying a shower fluid, and a swivel drive for driven swiveling of the swivel body, wherein the swivel drive includes a slide piston capable of being pressurized by a fluid pressure of the supplied shower fluid, which piston is arranged for translational movement between a first piston end position, corresponding with the first swivel body end position, and a second piston end position, corresponding with the second swivel body end position. Illustratively, the slide piston is arranged with a translation directional component in parallel to the swivel axis, and/or the swivel drive includes a transmission element in the form of a slotted guide mechanism between the slide piston and the swivel body, wherein the transmission element transmits the translational movement of the slide piston into a swivel movement of the swivel body, and/or the shower outlet in the rest position of the swivel body is swiveled away from a visible face of the swivel shower, and a swivel angle stroke from the first to the second swivel body end position is at most 90.

A fluid metering valve includes a valve needle that is actuatable by an electromagnetic actuator that includes an armature guided on and along a longitudinal axis of the valve needle with a movement limited by a stop surface on the valve needle. A projection of an edge of the stop surface extends into a projection plane, perpendicular to the longitudinal axis and at which the armature and stop surface are in contact temporarily during operation, through an opening of a conduit of the armature, dividing the opening into an inner surface on one side of the projection and an outer surface on the other side of the projection. A fluid exchange between inside and outside of an area between the stop surface and armature is via a path through the inner surface, conduit, and outer surface when the armature is in contact with the stop surface at the projection plane.

A valve for metering a fluid. An armature of the electromagnetic actuator is movable along a longitudinal axis of a valve needle, the movement of the armature relative to the valve needle being limited by a stop surface on the valve needle. The armature has a passage channel. The stop surface is on a stop element. The stop element and the armature are such that during operation there always remains an intermediate space, adjoining the valve needle, between the stop element and an end face of the armature facing the stop element. The stop surface lies, in a contact region, on the end surface of the armature facing the stop element when the armature and the stop surface come into contact during operation, the contact region being situated between the intermediate space and an opening of the passage channel when the armature and the stop surface come into contact.

A piston cooling jet includes a first body and a second body. The first body includes a housing having an inlet fluidly coupled with nozzle outlets. The second body is coupled to the first body to form an interior chamber disposed inside the first body and the second body. The interior chamber is fluidly coupled with the inlet and the nozzle outlets. The interior chamber directs fluid received via the inlet through the nozzle outlets and out of the piston cooling jet assembly in a direction towards a spray target.

In a spray nozzle with a nozzle housing including a dosing chamber for accommodating a release agent to be sprayed into a mold via a discharge line including a check valve and a nozzle body and a venting unit integrated into the nozzle housing for venting air from the spray nozzle, the volume of the dosing chamber is adjustable and the venting unit is activatable by an activation signal by which the venting unit is moved from a dysfunctional position to a venting and opening position in which the check valve is held open by the venting unit for venting the dosing chamber and the discharge line, via the nozzle body.
