Abstract: A control system and method for a thermal circuit that includes a control unit (1) and a valvular device which regulate the passage of a heat transfer fluid (6) through the inside of a thermal circuit, and a thermoelectric element (3) powering the control unit (1) from the heat of the heat transfer fluid (6). The control unit (1) and/or the valvular device are configured to regulate the circulation of the heat transfer fluid (6) through the inside of the thermal circuit, in order to always maintain a sufficient minimum flow to assure, at all times, the electric power supply of the control unit (1). The method includes using a control system to carry out regulation of the circulation of the heat transfer fluid which assures the electric power supply of part or the entire control system.

Abstract: One embodiment of the present invention is a method for setting and controlling temperature of a device that includes: (a) thermally contacting the device to a heat transfer apparatus, the heat transfer apparatus having an apparatus intake to receive thermal transfer fluid, an apparatus exhaust to output thermal transfer fluid, and a conduit to conduct thermal transfer fluid from the apparatus intake to the apparatus exhaust through the heat transfer apparatus; (b) flowing a first thermal transfer fluid in a first thermal control circuit at a first temperature, and flowing a second thermal transfer fluid in a second thermal control circuit at a second temperature; (c) at a first predetermined time, directing the first thermal transfer fluid to flow to the apparatus intake, and from the apparatus exhaust back to the first thermal control circuit and the second thermal transfer fluid to flow in the second thermal control circuit without flowing to the apparatus intake; and (d) at a second predetermined time, di

Abstract: A thermal valve assembly for a transmission is provided. The thermal valve assembly includes a body having a base portion having a plurality of opposing sidewalls extending therefrom. A cover is mounted with respect to the body and operates to at least partially close the body to form a volume. The base portion defines an inlet orifice, while at least one of the plurality of opposing sidewalls at least partially defines an outlet orifice. A plate is operable to selectively close the inlet orifice. A bi-metallic spring member is disposed at least partially within the volume. The bi-metallic spring member is operable to bias the plate against the base portion. Additionally, the bi-metallic spring member has a variable stiffness characteristic responsive to temperature.

Abstract: The present invention has a by-pass thermostat assembly (1) that is connected to the oil circulation system of an automatic hydraulic transmission system of an internal combustion or other engine. The assembly includes a block or a case (4) with an inner housing (5) to locate a thermostatic valve within a casing (7) that acts as a piston sliding along the housing, and being biased by a spring. The housing (5) is covered by an end plug (11).

Abstract: An apparatus and method is provided to evacuate liquids from a water jacket of an enclosed clamber. An electronic valve, such as a solenoid can be actuated remotely to open and allow liquids to evacuate. A controller can also be used to actuate the solenoid or at a period of time or at an event.

Abstract: A regulating insert for mounting in valves includes a dynamically flow regulating body, with the body having a first housing that is disposed within a second housing. A coil spring is arranged about an axis thereof, and a first end of the coil spring engages a slidable bottom cup provided with at least one inlet opening for liquid in its wall. The opening has an adjustable flow area. The second end of the coil spring opposite the first end engages a partly closed end of the second housing. The partly closed end has a cylindrical opening that provides a seat for a valve cone situated within the second housing. The position of the valve cone is regulated by first means via an activation means.
