  • Patent number: 9404481
    Abstract: Between a movable core chamber and a fuel supply passage, a needle guide slidably supports a needle fixed to a movable core. 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: 9273572
    Abstract: An aftermarket modification for diesel engines that operate in cold environments particularly those using a liquid-to-air oil cooler. Engine oil can be routed to a bypass module having a thermostatic element that directs the oil to bypass the oil cooler and return to the engine if the engine oil is below the desired temperature. Once the desired oil temperature is reached, the thermostatic element moves toward a closed position to direct oil through the oil cooler. A pressure bypass element can be incorporated into the bypass module. If the pressure differential between the inlet and outlet of the cooler exceeds a set point, the bypass element moves toward an open position to direct a portion of the oil to bypass the oil cooler.

    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: 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.

  • Patent number: 8833314
    Abstract: A cooling system for a combustion engine (1) includes a pilot line (12) which has an inlet (12a) to receive coolant from a line (3) of the cooling system and a thermostat (6) a sensing element (6b) for monitoring the temperature of the coolant in the pilot line (12) and a valve (6a). A thermal device (13, 26, 31) in contact with the coolant in the pilot line (12) at a location upstream of the sensing element (6b). A control unit (15) estimates when it is appropriate to alter the coolant's operating temperature in the cooling system and, at such times, activates the thermal device (13, 26, 31) so that it warms or cools the coolant in the pilot line (12).

  • Patent number: 8794254
    Abstract: High pressure gas vessels can have a sensitivity to temperature of the compressed gas. Over-temperature conditions in particular may cause decreased durability and/or vessel damage, including gas leakage to the environment. Articles of manufacture, methods, and systems are provided for over-temperature protection using a passive device. The passive closing device does not require electrical power and no controller, sensors, or wiring is needed. This affords cost savings in comparison to other systems. Pressure vessels using the passive closing device can protect themselves, independent of the compressed gas fueling station configuration.

  • Publication number: 20140196801
    Abstract: A multifunctional restrictive valve for controlling the flow of water therethrough. The valve has a main body with a flow channel through the main body. The main body receives water upstream thereof through an inlet port and passes it out through an outlet port at the downstream end of the body. A flow control assembly is located in the flow channel and includes a temperature sensor/actuator acting on a piston to move, when the temperature sensor heats up the piston, to block water flow control ports. The flow control assembly also includes an override feature wherein the piston is located within a slide and the flow control ports are located in the slide. By moving the slide away from the piston when the piston is blocking the flow control ports, the temperature sensor and piston may be overridden and flow may resume through the main body.

  • Patent number: 8752571
    Abstract: The valve assembly includes a body having a communication passage with an inlet and an outlet and a combustion chamber having a propellant and one or more openings, an igniter in communication with the propellant, and a valve means movable within the body. The igniter is adapted to ignite the propellant to provide a force to move the valve means from a closed position to an open position. The valve means has a first restricting element to restrict and permit passage of a pressurized gas through the outlet and a second restricting element to restrict and permit passage of heat from the burned propellant through the openings of the body, wherein the heat/gases cause a pressurized gas within the receptacle to expand causing the gas to quickly expunge from the receptacle. A biasing means may be used with the valve means to retain the valve means in the closed position.
