An air dryer having a heater element associated with its valves to prevent freezing at cold temperatures. The air dryer includes a temperature sensor and an electronic controller that reads the temperature sensor and inhibits actuation of the valves whenever the temperature of valves is below freezing or a predetermined temperature that indicates a risk for freezing until the valves have been sufficiently warmed by the heater to avoid freezing during operation.

The antifreeze flows through the determined one or more system components to be winterized.

Gas safety valve includes: a valve body which defines a flow pipe and in which a shutter is located, movable between an open position and a closed position to, respectively, allow and prevent the flow of an operating gas through the flow pipe; first thrusting apparatus for the shutter in the closed position; a retaining mechanism to maintain the shutter in the open position, the release of which can be forced by a release so as to release the shutter; a control element movable between a locking position and a released position to, respectively, prevent and allow the release of the retaining mechanism; a first actuator device to force the control element into the released position. The first actuator device includes an actuator body movable between a rest position to allow the control element to maintain the locking position and a working position to force the control element into its released position, a retaining spring to force the actuator body into a rest position and a shape memory spring to overcome the force of the retaining spring and force the actuator body into the working position when the temperature of the shape memory spring is within a predetermined temperature range.

The present invention is directed to improved assembly for transporting flammable fluids. In an example, the assembly comprises a conduit, a liner, and a core. The liner comprises a material that contracts in response to an elevation in temperature. In an example, the liner comprises a material that expands in response to an elevation in temperature.

A system includes a first valve fluidly connected to a first vessel and a second valve fluidly connected to a second vessel. The first valve includes a body and a piston. The body includes first and second ports and a bore having a longitudinal axis. The first port is in communication with the bore and an interior of the first vessel. The second port is in communication with the bore, the second valve, and an atmosphere exterior to the first vessel. The piston is movable along the longitudinal axis of the bore. A first position of the piston blocks the first port; a second position of the piston allows fluid communication between the first and second ports. The first valve is configured so that fluid pressure from the second valve, communicating through the second port, urges the piston to the second position.

A system for storing a pressurized gas in a motor vehicle is provided, having a storage container and at least one thermally activatable safety valve for emptying the storage container. The safety valve activates automatically at a corresponding high temperature. The storage container has an additional activatable emptying device, which has an interface for an external energy source. The interface can be connected to the external energy source in order to empty the storage container in a targeted manner. Also provided is a method for emptying a storage container for a pressurized gas in a motor vehicle.

A valve device for a fuel filter module has a first fluid channel through which fuel flows only in recirculation mode of the fuel filter module and a second fluid channel through which fuel flows only outside of the recirculation mode. The first fluid channel extends inside the second fluid channel. The first and second fluid channels are coaxial to each other. A fuel filter module switchable into recirculation mode and out of recirculation mode is provided with a control valve that has a valve bore and a valve device arranged in the valve bore, wherein the valve device has a first fluid channel through which fuel flows only in recirculation mode and a second fluid channel through which fuel flows only outside of the recirculation mode. The first fluid channel extends inside the second fluid channel, and the first and second fluid channels are coaxial to each other.

Disclosed herein are flow control devices including at least one remote temperature sensor configured to determine first temperature data associated with air outside of a dwelling; a valve configured to control a first flow rate of the liquid flowing from an inlet of the supply pipe along a controlled liquid flow path by moving a valve position from a closed position to an open position; a flow control component in fluid communication with the valve, and configured to control a second flow rate of the liquid flowing from the valve; at least one internal temperature sensor configured to determine second temperature data associated with air inside the dwelling; a controller communicatively connected to the temperature sensors and configured to control operation of the valve based at least on at least one of the first temperature data and the second temperature data; and a housing configured to contain the flow control device components and further configured to releasably attach to a spigot or spout of a supply pipe. Also disclosed herein are methods for using the disclosed devices.

According to an example, a system for managing a fluid condition in a pipe includes a controller to receive temperatures of the pipe detected by the temperature sensor over a period of time. The controller may determine, based upon the temperatures of the pipe over the period of time, a temperature profile of the pipe and may determine that the temperature profile of the pipe indicates that a freezing onset event has occurred. The freezing onset event may include a transition from a drop in temperature to an increase in temperature, in which the temperature during the transition is below a freezing point temperature of a fluid contained in the pipe. The controller may further trigger at least one of an alarm and an activation of a first freezing prevention device in response to the determination that the freezing onset event has occurred.
