  • Patent number: 9915959
    Abstract: A thermostatic valve for a diesel fuel system includes a valve housing and a valve element movable within the housing between a position directing heated diesel fuel returning from an engine to the inlet of a fuel pump and a position dumping the fuel into a reservoir where the fuel mixes with lower temperature fuel. A temperature responsive thermostatic element moves the valve element in response to the temperature of the diesel fuel. A temperature relief valve is provided in the housing to dump the returning fuel into the reservoir if the temperature reaches a temperature indicating overheating of the fuel. The temperature relief valve is a bi-metal valve mounted in an end wall of the valve housing.

The needle guide has a communication hole which fluidly connects the movable core chamber and the fuel supply passage. An opening sectional area of the communication hole is defined in such a manner that a fuel discharged amount decreases as an energization start time of a coil is delayed. In a suction stroke, it is restricted that the movable core and the needle bounce toward the fixed core after the needle biases a suction valve toward a stopper by means of a biasing force of a second spring. A relationship between the energization start time of the coil and the fuel discharged amount is properly maintained, so that the fuel discharged amount of the high-pressure pump can be controlled correctly.

  • Patent number: 8899190
    Abstract: An engine assembly includes an engine block that defines a cylinder bore. A reciprocating piston is disposed in the cylinder bore, and has a first side and a second side. The first side cooperates with the engine block to partially define a combustion chamber, and the second side is opposite the first side. A piston squirter is disposed adjacent to the second side of the piston and configured to expel a received flow of engine oil onto the piston. A thermal fluid valve is disposed in fluid communication with the piston squirter and is configured to selectively restrict the flow of engine oil to the piston squirter in response to a temperature of the engine oil.

  • Patent number: 8881991
    Abstract: A wiring arrangement for protecting a bleed air supply system of an aircraft against overheating is associated with a bleed air supply system. The bleed air supply system includes a bleed air source, a bleed air feed, a shutoff valve arranged in the bleed air feed and a leakage monitoring device with a monitoring control device, which is connected via a shutoff circuit to the shutoff valve in such a way that the shutoff valve is closed when the shutoff circuit is interrupted. The wiring arrangement includes a thermal switch, which is connected in series with the shutoff valve and the monitoring control device to the shutoff circuit and which, once a predetermined limit temperature has been exceeded, interrupts the shutoff circuit.

    Abstract: A system for collecting and accumulating excess water from one or more in-building sources and delivering it to one or more flushing toilet tanks and possibly also to one or more other in-building consumption devices, such as washing machines or utility faucets. The in-building sources may include any of condensate from an air conditioner, cool water in a hot water supply pipe emerging during initial flow, treated waste water and collected rain- or snow water. At the heart of the disclosed system is an accumulation tank of large capacity, having at least two inlets and at least one outlet. One of the inlets is connected to the main water supply system and includes a valve, configured to let fresh water flow into the main tank whenever the level of the water stored therein falls below a given height.

  • Publication number: 20140318640
    Abstract: A lubrication system thermostat for controlling the flow of oil in a lubrication system includes a valve and an actuator. The valve is configured to modulate between an unmodulated position and a modulated position, each of which may be in an open position or a closed position. In the open position, at least a portion of the oil flow is unobstructed, and in the closed position, the oil flow is substantially blocked. The actuator is configured to modulate the valve. The actuator includes a thermal element configured to generate mechanical displacement when subjected to a temperature change such that the valve is movable from and returnable to the unmodulated position. The lubrication system thermostat may be in a normally-open configuration, in which the unmodulated position is the open position, or a normally-closed configuration, in which the unmodulated position is the closed position.

  • Publication number: 20140311592
    Abstract: It is a temperature control outlet device, including parts as body, faceplate communicating with the outlet end of the body, and the outlet assembly inside the body. The said outlet assembly includes a valve connected to the said body The said valve includes a mainstream and a diversion vent. There is a valve rod inside the channel of the said mainstream, which will open/close the said mainstream flow through a bias spring on the bottom and a memory spring on the top. The said diversion vent is connected to the diversion assembly and then makes a diversion channel. The said diversion assembly includes a switching rod with one end connected to a captured spring and the other end connected to a button so as to open/close the diversion channel. The invention of the claimed temperature control device will automatically stop outflow after running out cold water so as to save hot water and time in a way to make it more practical.

  • Publication number: 20140262153
    Abstract: Disclosed is a valve for controlling a flow rate of an inlet fluid. The valve includes a housing portion that has at least one fluid inlet and at least one fluid outlet and at least two containers that are positioned at least partially within the housing portion. The at least two containers define respective interior portions for receiving a working fluid. The interior portions are in fluidal communication with each other, and at least one of the containers is arranged such that the working fluid in that container can exchange thermal energy with the or another inlet fluid. A change in a temperature difference between the working fluid in the respective interior portions of the containers and within a predetermined range of temperature difference causes a quantity of the working fluid to be transferred in or out of at least one of the containers.
