摘要:
The invention relates to various ways in which to integrate control valves into the structure of a heat exchanger. Accordingly, there is provided a heat exchanger assembly comprising a heat exchanger and a valve integration unit. The heat exchanger includes a plurality of alternating first and second fluid passages in heat exchange relation, and at least one inlet manifold and one outlet manifold interconnected by one of the plurality of first or second fluid passages, the valve integration unit being fixedly attached to heat exchanger and comprising a fluid passage in fluid communication with at least one of the inlet and outlet manifolds. A valve mechanism is mounted within the valve integration unit in fluid communication with the fluid passage, the valve mechanism controlling the flow of a heat exchange fluid through said fluid passage.

A valve assembly for a water circulation system includes a valve body defining a bypass passage between a hot water side and a cold water side of the valve body. The bypass passage has a valve seat therein. A bypass valve is received within the bypass passage. The bypass valve restricts the flow of water through the bypass passage based on a temperature of the water in the bypass passage. The bypass valve is variably positionable with respect to the valve seat to control a bypass shut-off temperature of the water.

The present invention is directed to a fuel supply with an environmentally sensitive valve. The environmentally sensitive valve is sensitive to the environmental factor(s) such as temperature, pressure or velocity. The valve may be configured so that the valve automatically resets when the environmental triggering event no longer exists.

Thermostatic gas valve with a pressure regulator The thermostatic gas valve (1) is adapted for delivering gas flows (7′,8′) to a main burner and to a pilot burner of a heater appliance and comprises a valve body (3) with a plurality of internal gas distribution chambers (4,5,5′) interconnected to a manual valve (11), to a main flow (7′) thermostatic modulating device (12), and to an electromagnetic safety valve (9) energised by a thermocouple (10), between a gas inlet duct (6) and outlet ducts (7,8) for said flows (7′,8′). An inlet pressure (Pe) regulator device (2) provided with a diaphragm type stabilising valve (18,19), is inserted in said inlet duct (6) in direct communication with the safety valve (9) via a flat conduit (27) under a valve body cover (14).

The compensation element is compensating for temperature-conditioned length changes of an object. An injection valve that is fully functional in the entire range of the operating temperatures of a motor requires a device that compensates thermally conditioned length changes of the mechanical components (piezo-electric actuator, valve lifter, housing, etc.). This device should be capable of absorbing great forces and allow a stiff bearing of the actuator. The compensation element (3) has an oil-filled chamber (21) is composed of an actuator-side upper part (18), of a lower part (19) supported on a stiff bearing (valve housing 17), and of a structure (annular seal element 20) sealing the chamber (21) and yielding in an axial direction. Since the compensation element (3) is fitted into an annular holder (4) with little lateral play, every temperature-conditioned change of the oil or, respectively, chamber volume results in a displacement of the upper housing part (18) in an axial direction that is proportional to the volume change. As a result of a corresponding dimensioning of the chamber height, temperature-conditioned length changes of the valve housing (4) and of the piezo-electric actuator (2) can be compensated using the extremely compactly constructed and comparatively rigid compensation element (3).
摘要:
This shower head serves to replace existing shower heads, and when the water becomes too hot for safety, it is so designed, that it will stop the hot water flow from striking the bather. It consists primarily of a fixed thermostat, which, when expanded, will cause a disc attached to a piston to be, by water pressure, urged against an opening, to cut off the water flow on the bather, and the hot water is then shut off at its source by the bather. The head further includes a lower passageway leading to a depressible relief valve, for releasing the hot water from the thermostat area, so as to enable the thermostat to reset.
