Disclosed is a motor vehicle solenoid valve (10). The solenoid valve includes a fixed body (20) intended to be mounted in a hydraulic system of the vehicle, a cylindrical coil supporting unit (40) mounted on the fixed body, a mobile body (30) slidingly mounted in the fixed body through the coil supporting unit and at least a first coil winding (50) arranged about the coil supporting unit and suitable for generating a magnetic field for control of the sliding of the mobile body. The solenoid valve further includes a second coil winding (60) arranged about the first coil winding in order to contain the magnetic field generated by the first coil winding.

A flow control valve assembly has at least one manifold having an inlet flow port, an outlet flow port, and a flow channel provided there between, the flow channel having an inlet chamber, a variable area chamber and an outlet chamber, with fluid flowing from the inlet flow port to the inlet chamber, the variable area chamber and the outlet chamber, in that order, before exiting the outlet flow port. The flow control valve assembly further includes a float assembly having a fitting, a float extending through the flow channel from the fitting and which is limited for its movement inside the variable area chamber, a measuring device that measures the displacement of the float and which is secured to the fitting and positioned outside the flow channel, and a connecting rod which connects the float to the measuring device and extends through the flow channel.

According to one example, a beverage dispensing device includes a beverage vessel configured to hold a beverage within the beverage vessel. The beverage vessel has a hole that extends entirely through a bottom portion of the beverage vessel. The beverage dispensing device further includes a plug seat located within the beverage vessel and positioned around the hole, and a weighted plug located within the beverage vessel and positioned against the opening in the plug seat. The weighted plug and plug seat are configured to prevent the beverage from draining through the hole by creating a liquid-tight seal. The beverage dispensing device further includes a lever coupled, at least indirectly, to the beverage vessel. The lever is configured, when activated, to move the weighted plug in relation to the plug seat so as to break the liquid-tight seal. The weighted plug is securely coupled to the lever.

A submersible pneumatic canister pump system for pumping liquid from a tank or underground location by incorporating a floating ball valve inside the pump for preventing air from exiting with the liquid discharge. The floating ball valve is located near the lower end of the pump and communicates with the discharge pipe. When liquid level approaches the lower end of the pump a ball of lighter density than the liquid rests on a seat and prevents further discharge of liquid and the passage of air out of the pump. Also shown are various pump control arrangements that can be used to operate the pump.
