摘要： The temperature-responsive fluid flow control apparatus of the present invention comprises: a housing installed between the inlet and the outlet of a fluid pipe in which a fluid flows; a valve block installed inside the housing to allow inflow of the flowing fluid in the housing and to discharge a portion of the flowing fluid to the outside according to the change in the internal pressure; and a temperature-responsive device for generating a pressure difference in the valve block according to the temperature change of the temperature-responsive fluid filled therein. The temperature-responsive fluid flow control apparatus prevents the fluid flowing pipe from freezing by discharging a potion of the fluid flowing in the housing to the outside, when the temperature of the temperature-responsive fluid reaches a preset temperature as the external temperature drops.

摘要： A hot and cold water mixing valve including a temperature adjusting dial D, and a cylindrical casing 1 having formed therein a hot water inlet a and a cold water inlet b is provided with a control valve member 2 in which one end is subjected to a load from a biasing member 4 and the other end is subjected to a load from an actuator 5, and an opening/closing ratio between the hot water inlet a and the cold water inlet b is changed by balancing between the loads applied by the biasing member 4 and the actuator 5, to adjust a mixture ratio between the hot water which flows in through the hot water inlet a and the cold water which flows in through the cold water inlet b, and a temperature adjusting means (8, 900) whose one side is fixed to the temperature adjusting dial D and whose other side adjusts a position of the control valve member 2 through the biasing member 4. A tapered skirt portion 94 which spreads in a radial direction is formed at an end on the control valve member 2 side of the temperature adjusting means (8, 900).

摘要： A movable valve body (70) for determining a mixing ratio of hot water and cold water is actuated by using a heat-sensitive coil spring (80) made of a material the spring constant of which changes with temperature, so as to eliminate the deviation of the actual temperature from a target temperature. When the temperature deviation cannot be eliminated by the temperature control by the coil spring (80) alone, it is eliminated by feedback control. A control gain K of this feedback control is determined on the basis of the rate of change in the spring constant in order to prevent hunting, etc. When the temperature deviation is eliminated by the feedback control, the relation between the target temperature and the present load adjustment quantity is stored, and the latter is used when the next target temperature is set. The feedback control is not carried out at the start of tapping or at the time of the change of the target temperature until the temperature deviation becomes smaller than a threshold value (TR1) in order to prevent hot water from being supplied after dead water has been discharged.

摘要： A thermally responsive pressure relief valve (26) using a bimetallic valve disc (28) as a component. The bimetallic valve disc (28) is used as a temperature sensitive valve seal. When temperatures go beyond the set point of the disc (28), it opens the valve (26) with a snap acting motion permitting pressure to be vented through the valve (26). The valve disc (28) automatically resets and reseals the valve (26) when temperatures return to the reset of the disc (28).

摘要： A fluid level control valve has a base [102] with an aperture [126] formed therein. A cover [120] is slidingly disposed over the aperture [126] and is biased by a thermostatic element [108] in a direction tending to close the aperture [126]. In one embodiment the thermostatic element [108] is an elongated strip having one end captured by tabs projecting from the base, and an opposite end is captured by a bracket formed on the base. The thermostatic element [108] is formed with a V-shaped force imparting portion which is aligned with the cover [120] and the position of the bracket is adjustable to place a selected force on the cover [120] through the thermostatic element [108]. The calibrated valve is then fixedly attached to a housing with the aperture aligned with an aperture in the housing. In another embodiment a U-shaped thermostatic strip has one end mounted on the base with its opposite end biased against the cover.

摘要： The invention relates to a valve system (1) comprising a valve body (6) which is arranged in a valve housing (2) and is actuatable by means of a shape-memory element (20) which is movable from an undeformed rest state to a tension deformed state and is again transferred to the rest state. The inventive valve system is improved by a force deflecting device which enables the shape-memory element (20) to actuate the valve body exclusively during the transfer thereof to the tension or rest state.
