A valve assembly consists essentially of a valve body having an inlet port and an outlet port; a valve retainer at least partially housed within the valve body; a valve poppet positioned within the valve body; a magnet affixed within the valve body near the valve body inlet port; and a solenoid coil mounted around the valve body.

A fluid-distribution system for use with one or more vehicle sub-systems in a vehicle includes a first transfer conduit, a second transfer conduit, and a valve unit. The first transfer conduit defines a first interior space and is coupled to a fluid source to receive and direct a fluid through the first interior space. The second transfer conduit defines a second interior space and is spaced apart downstream from the first transfer conduit. The valve unit extends between and interconnects the first transfer conduit and the second transfer conduit.

A valve assembly includes a valve body defining a fluid inlet in fluid communication with a fluid outlet. The valve body has an inner body surface defining an interior chamber extending between the fluid inlet and the fluid outlet. A valve element is disposed within the interior chamber and rotatable through a range of positions relative to the outlet providing a high level of precision control of a fluid flow rate through the valve assembly. A valve seat with a seal is positioned around a valve element. The valve seat is configured to self-adjust its inner radial diameter to correspond to the outer radial diameter of the valve element to maintain a portion of an inner seat surface in contact with an outer valve surface of the valve element through the range of positions.

Devices, systems and methods for leak detection are provided herein. Also provided are devices, systems and methods for monitoring and/or measuring fluid usage. In some aspects, a system comprising a sensor, a processing system, and a platform are provided. In some aspects, the sensor may be coupled to a spinning device. The sensor can be configured to detect fluid data, which can comprise, for example, displacement data of liquid and/or movement data associated with the liquid in a container and/or flow data associated with a flow of fluid in a conduit. The processing system can be coupled with the sensor and configured to communicate the fluid data. The platform can comprise an application communicatively coupled to one or more databases storing evaluation data (e.g., known pattern data) and configured to receive the fluid data and determine if there is a leak.

Fluid flow control valve comprising a tubular body extending in a longitudinal direction with a fluid inlet and a fluid outlet situated respectively at the two longitudinal ends of the body, the valve comprising a nozzle and a piston connected to the body, the piston being housed in the body, the nozzle being made up of a part provided with a fluid passage having a calibrated dimension, the passage emerging at one end of the nozzle and forming a seat, said seat being situated against a terminal end of the piston forming a shutter preventing the flow of fluid in the closed position of the valve, the piston comprising a body defining a passage for the fluid in the body for the flow of the fluid between the inlet and the outlet, the body of the valve consisting of a material having a different expansion coefficient from the piston or the nozzle, the valve comprising a heating member which, depending on the heating power delivered, makes it possible to separate the end of the nozzle and the piston by differential expansion, to allow the flow of fluid between the inlet and the outlet in an open position of the valve, characterized in that the terminal end of the piston comprises a ball that is crimped into the body of the piston.

A solenoid valve has a valve plunger which is guided in a passage bore of a valve housing. The valve plunger with its valve closing element is held in a basic position by a restoring spring. The basic position opens up a valve passage in a valve seat. The valve plunger is arranged between an inlet and an outlet channel in the valve housing. A magnet armature provides actuation of the valve plunger. An inlet chamber is connected to the inlet channel between the passage bore and the valve seat. The valve plunger protrudes into the inlet chamber by way of a step section. As a result of being hydraulically impinged on by the pressure medium of the inlet channel an axial force is generated on the valve plunger that acts oppositely to the closing direction of the valve plunger.
