An actuator for controlling a fluid path includes an actuator having a seat part, either a fluid-valve membrane or a movable part, and a magnetorheological elastomer that changes form when a magnetic field changes. This causes the path to open or close.

The present invention controls the pressure and flow rate of fluid, in order to obtain uniform performance, configure a closed loop magnetic circuit so as to include an electromagnet, a flapper, and a yoke material, and elastically deform the flapper itself by Maxwell attractive force generated between a magnetic pole of the electromagnet and the flapper to make the separation distance between the nozzle and the flapper variable. As opposed to a rigid flapper structure that swingably moves around a supporting point, like a conventional servo valve, the electromagnet, the magnetic pole, the nozzle, the flapper, and the like are arranged such that a change in magnetic gap directly leads to a change in air gap.

A valve has a housing which has at least two fluid openings, through which fluid can flow, and a further opening, at least one valve seat which is assigned to one of the fluid openings, and at least one closure member which is adjustable to release and/or close the at least one valve seat, the at least one valve seat which adjoins a cavity through which fluid can flow being formed on a housing part. The valve includes a sensor device which closes the opening in a fluid-tight manner and can acquire data about the fluid is arranged in the further opening. A valve island is furthermore described.

A diaphragm valve includes a valve housing in which a switching rocker, which is pivotable about a pivot axis and which interacts with a control diaphragm for opening and closing at least one valve channel, is arranged. The pivot axis is defined by a mounting web, on which the switching rocker bears in a pivotably movable manner. The mounting web is an integral constituent of a mounting unit, said mounting unit being fastened to the valve housing in a drive chamber by way of fastening measures. Without the fastening measures, the mounting unit can be displaced in order to adjust a desired height distance of the mounting web.

A rocker valve comprising a rocker valve mechanism in a valve body. The mechanism comprises a single pivot arm to which first and second plungers are pivotally fixed to act in opposition. The rocker valve includes a flexible seal member extending laterally across the first and second fluid ports and having a first sealing region attached to a plunger head of the first plunger and a second sealing region attached to a plunger head of the second plunger. When the single pivot arm is pivoted relative to the valve body, a rotation of at least one of the first and second plungers about its respective fixed pivot is constrained solely by the flexible seal member such that a lateral position of the plunger head is automatically adjusted by the flexible seal member to balance tensile forces in the flexible seal member around the plunger head.

A solenoid valve has a housing which comprises a first and a second housing part, wherein a flexible diaphragm is arranged between the first and the second housing part. A movably mounted actuating element is provided which is connected to the diaphragm and detaches the diaphragm from a valve seat in an operating position of the first and the second housing part upon movement into an open position, and which presses the diaphragm onto the valve seat upon movement into a closed position. The first and the second housing part can take up a service position in which the diaphragm is accessible. The diaphragm is connected with a positive fit to the actuating element in a nondestructively detachable manner such that in the service position, the diaphragm can be removed from the actuating element by releasing the positive fit and can be connected thereto by establishing a positive fit. An assembly and a method of replacing a diaphragm are furthermore proposed.

A solenoid valve having a valve housing in which a flexible diaphragm is accommodated, having a rocker for deforming the diaphragm, wherein a first orifice of a first fluid channel serves as a first valve seat against which the diaphragm is pressed in a sealing manner in the first functional position of the rocker and which valve seat is released by the diaphragm in the second functional position of the rocker, and further comprising a magnetic drive for moving a linearly movable armature part which is provided with an intermediate part for transmitting force to the rocker and which passes through the intermediate part, wherein the intermediate part is connected to the end region in a force-locking and/or substance-locking manner and/or is supported in a form-locking manner on an annular collar of a retaining part fixed to the end region in a force-locking or substance-locking manner.

A fluidic valve device intended to be arranged in a fluidic circuit, the device notably including a first switching assembly including a first compartment defining a first internal space and a first permanent magnet arranged with the freedom to slide in the first internal space, a second switching assembly including a second compartment defining a second internal space and a second permanent magnet arranged with the freedom to slide in the second internal space, the first permanent magnet and the second permanent magnet being arranged relative to one another in such a way as to be in a first state of magnetic interaction, making it possible to obtain a first stable mechanical configuration or in a second state of magnetic interaction, it possible to obtain a second stable mechanical configuration.

A shower system includes a showerhead, which includes a first diverter that is configured to deliver water to a plurality of showerhead outlets. The first diverter is actuatable to change a showerhead water discharge mode of the plurality of showerhead outlets. A diverter actuator is actuatable to actuate the first diverter and thereby change the showerhead water discharge mode of the plurality of showerhead outlets. The shower system further includes a handshower, which includes a second diverter that is configured to deliver water to a plurality of handshower outlets. The second diverter is actuatable to change a handshower water discharge mode of the plurality of handshower outlets. The shower system further includes a user interface that is configured to be actuated by a user to selectively and independently (1) deliver water from the handshower to the diverter actuator to actuate the diverter actuator, and (2) actuate the second diverter.
