An assembly includes an inlet tube and an outlet tube. The assembly includes a solenoid assembly having a plunger movable between an open position in which fluid is permitted to flow from the inlet tube to the outlet tube and a closed position in which fluid is inhibited from flowing from the inlet tube to the outlet tube, the solenoid assembly having an induction coil surrounding the plunger. The assembly includes a Hall effect sensor that detects a magnetic field of the solenoid assembly. The assembly includes a computer in communication with the Hall effect sensor, the computer having a processor and memory that stores instructions executable by the processor to identify a resistance of the induction coil based on data from the Hall effect sensor, and to determine whether the plunger is at the closed position based on the identified resistance of the induction coil.

An appliance comprising an air flow path extending from an air inlet, by which water and air are introduced to the appliance, to an air outlet. A water separator is positioned in the air flow path, which, when in operation, separates the water from the air. A water storage chamber is in fluid flow communication with the water separator, which stores the water separated from the air. The appliance also comprises an automatic closure member movable between an open position and a closed position. When the automatic closure member is in the open position, the water storage chamber is in fluid flow communication with the water separator; when in the closed position, the water storage chamber is isolated from the water separator. The automatic closure member moves from the open position to the closed position when the pressure in the water separator increases above a predetermined level.

A fluid dispensing device includes a container coupled between a bottle and a discharge tube for forcing the fluid to flow through the discharge tube without gravity, a base member is disposed in the container, a housing is engaged in the container and movable toward and away from the base member, a spring biased plug controls the fluid to flow out of the housing, a cap and a casing are attached to the container, a spring biased valve piece is engaged in the casing for engaging with the cap and for controlling the fluid to flow through the cap, a magnetic member is attached to the casing, and a coil is attached to the container to act with and to move the magnetic member in the container.

Apparatus and method to facilitate heat transfer fluid flow are disclosed herein. A flexible tube having first and second ends facilitates a heat transfer fluid to flow from the first end to the second end. Ferromagnetic material encircles at least an outside portion of a length of the flexible tube, and a plurality of coil windings encircles the ferromagnetic material. The flexible tube is to be compressed to reduce an amount of flow of the heat transfer fluid from the first end to the second end by expansion of the ferromagnetic material around the flexible tube, in response to an application of a current to the plurality of coil windings.

A manifold assembly for a camera wash system of an autonomous vehicle is disclosed. The manifold assembly includes a fluid inlet; a plurality of fluid injectors, each fluid injector configured to switch between an open state in which fluid passes through the fluid injector and aclosed state in which fluid does not pass through the fluid injector; a block member configured to hold the fluid injectors in a fixed position; and a rail member including a fluid passage in fluidcommunication between the fluid inlet and each fluid injector for providing a cleaning fluid to each of the fluid injectors.

A solenoid valve includes a valve housing having a first space that communicates with an inlet flow path and a second space that communicates with an outlet flow path. A solenoid is provided in the valve housing to surround the first space. A flow path guide is provided in the first space and has an inflow path communicating with the first space. A plunger is rectilinearly moved in the flow path guide by the solenoid. A valve member is connected to the plunger and opens or closes the outlet flow path based on a plunger movement. A spring member provides elastic force allowing the valve member to move in a direction in which the valve member blocks the outlet flow path. A fluid guide part is formed in the plunger and guides a fluid, supplied into the inflow path via the first space, selectively to the second space.

A process component includes a first connection, a second connection, and an adjusting element arranged in a hollow space fluidically connecting the first connection to the second connection and that can be brought into a first position and second position in an axial direction within the hollow space. The component includes a permanent magnet, a first electrical coil, and a second electrical coil arranged in succession in the axial direction to create a simple process component whose size can be effectively scaled. The magnet, adjusting element, and a yoke form a first closed magnetic circuit in the first position and a second closed magnetic circuit in the second position. The first and second coil respectively compensate for the first circuit and the second circuit. The hollow space and adjusting element are shaped such that the valve can be penetrated by a fluid flow formed between the first and second connections.

A breathing assistance device includes a gas regulating valve. The gas regulating valve is operated by a linear actuator. The linear actuator may include a movable member that moves an obstruction member between an open position and a closed position. The linear actuator is isolated from a gas flow path through the valve.

A valve assembly includes a valve moveable between an open position where hydraulic fluid flow is permitted and a closed position where hydraulic fluid flow is blocked. A controller includes a magnetometer adapted to measure a magnetic flux through at least a portion of a solenoid linear actuator that moves the valve. A magnetic flux value measured by the magnetometer corresponds to a linear position of the regulating member relative to the port.

Disclosed is a magnetic valve, including: a valve body, provided with an installation cavity, a first valve port and a second valve port; a valve core, installed in the installation cavity and provided with a valve opening position and a valve closing position, a second cavity located at an outer periphery of a main body of the valve core and a third cavity located at a second end of the valve core, the first valve port is communicated with the third cavity and the second valve port is communicated with the second cavity; a core iron assembly, including a core iron, herein the valve core is fixedly connected with a first end of the core iron; an attractor, installed in the installation cavity and located at a second end of the core iron; and a balancing channel, extended along an axial direction of the valve core and the core iron.
