The invention relates to a 3-port valve for passing fluids therethrough, having a valve body, a port, a first sub-port and a second sub-port, with the port being adjoined by a main line which ends in a connecting region, said first sub-port having a first sub-port line that is connected to the connecting region, said second sub-port having a second sub-port line that is connected to the connecting region, with at least one valve member being arranged in the connecting region, which valve member can be displaced along a valve member axis between an opening position and a closed position thereof in the connecting region, so that, in a first valve position, the port is fluidically connected to the first sub-port, in a second valve position, the port is fluidically connected to the second sub-port, in a third valve position, the port is fluidically connected to both the first and second sub-ports, in a fourth valve position, the port is fluidically connected neither to the first sub-port nor to the second sub-port. The invention is characterized in that the valve body is formed from a high-tempered steel, or other suitable material, with the valve body being produced from a solid ingot and with the connecting region, the main port, the first sub-port line and the second sub-port line having been machined into the steel ingot. Heat transfer medium lines for passing a HTM therethrough are also machined into the same valve body to regulate the temperature of the fluid. Simultaneously or alternatively, electric heating cartridge receptacles may be machined into the valve body ingot.

A device for dispensing liquid onto a target area of a vehicle surface is described, and includes a mixing valve that is in communication with a pressurized fluidic supply system via a fluidic distribution system, and a controller. The mixing valve includes an outlet orifice that is disposed proximal to the target area, and the mixing valve includes first and second valve conduits that are fluidly connected to the outlet orifice via a mixing portion. The first valve conduit includes a first control valve, and the second valve conduit includes a second control valve. The fluidic distribution system includes a first fluidic conduit and a second fluidic conduit. The controller is operatively connected to the fluidic supply system, and the first and second control valves.

A solenoid comprises first and second coils connected to an electrical power supply circuit. In a first mode of operation the power supply circuit is arranged to provide a current flowing in opposite directions through the respective first and second coils, e.g. to produce a self-heating effect. In a second mode of operation the power supply circuit is arranged to provide a current flowing in the same direction through the respective first and second coils, e.g. to generate a magnetic force. In some embodiments, the power supply circuit includes a bridge rectifier or full wave rectifier connected to a bi-directional current driver.

A ventilation unit for a low temperature chamber with a tube-shaped base body, having a heating element, an inlet side end with an inlet opening and an outlet side end with an outlet opening, wherein the base body has a tapered form such that the inlet opening has a greater area than the outlet opening. The inlet opening can be located in a first front side plane and the outlet opening can be located in a second front side plane, wherein the first front side plane and the second front side plane are substantially parallel offset with respect to one another, and wherein at perpendicular projection of the first front side plane onto the second front side plane, the inlet opening and the outlet opening are disposed offset with respect to one another. The base body can have a mechanical valve configured to open under pressure induction.

A heated water valve provides electrical resistance heaters placed within flange connections of the valve to provide for an integrated heater valve assembly with good heat conduction and spreading capabilities that can prevent water valve freezing at low temperatures.

A vacuum valve includes a valve plate that covers an exhaust port of a vacuum chamber, and a poppet type actuator that drives the valve plate in an axial direction orthogonal to a surface of the vacuum chamber on which the exhaust port is provided. The actuator includes a shaft that is connected to the valve plate, a drive unit that is disposed side by side with the shaft in a radial direction of the shaft and includes a ball screw shaft and a drive source that rotates the ball screw shaft, and a connection part that connects the ball screw shaft and the shaft and moves in the axial direction together with the shaft to a position where the valve plate covers the exhaust port.

A valve includes a body with an inlet at a first end of the body, and an outlet at a second end of the body. A first electrically resistive heating element is located in the inlet and heats a first fluid source to a temperature above 0 degrees C. A second electrically resistive heating element is located in the outlet and heats a second fluid source to a temperature above 0 degrees C.

A heated valve is provided and includes a valve body having an inlet, an outlet downstream from the inlet and a valve section fluidly interposed between the inlet and the outlet, a valve element operably disposed within the valve section to assume and move between at least a first position at which fluid communication between the inlet and the outlet is prevented by the valve element and a second position at which the fluid communication is permitted and a heating system. The heating system is in operable communication with at least one of the valve body and the valve element and is configured to melt ice that could prevent movement of the valve element between the first and second positions.

A plumbing fitting includes a housing and a missing valve. The housing includes a first aperture, a second aperture, a third aperture, and a mixing chamber in fluid communication with the first aperture, the second aperture, and the third aperture. The mixing valve is disposed within the housing. The mixing valve includes a first flow control valve that is configured to control a first flow of fluid from the first aperture to the mixing chamber.

A temperature-controlled pressure regulator assembly includes a regulator having a regulator body, a valve seat, an inlet, an outlet, and defines a flow passage connecting the inlet and the outlet. A control element controls the device, a portion of the flow passage extends through a heat chamber, and a heater is positioned to heat the chamber thereby conveying heat to a fluid in the flow passage. A controller is electrically coupled to the heater and is coupled to a power source. A thermal cut-off fuse is coupled to a control circuit, with the thermal cut-off fuse arranged to electrically decouple the heater from the control circuit in response to a temperature exceeding a threshold, thereby deactivating the heater. The thermal cut-off fuse is disposed in a circular fuse holder and positioned adjacent the heater and adjacent a longitudinal center of the heat chamber.
