Abstract: A thermostat for controlling flow of a coolant fluid through an aperture, the thermostat including a temperature sensitive valve for controlling the opening and closing of the aperture, the temperature sensitive valve having: a valve body with a heat sensitive material and a displaceable pin, a lid configured to seal off the aperture, a support member, a flexible member located between the lid and the support member, and a position sensor configured to provide information indicative of the position of the temperature sensitive valve or a part thereof

Abstract: The present disclosure provides thermostats and thermostat housings with a support frame that is linearly displaceable relative to an aperture of the thermostat, for modifying operational characteristics of the opening and closing of the aperture by a valve actuated via a thermal-actuator with an extendible pin configured to be pressed against the support frame for moving the valve to open and close the aperture.

Abstract: There is provided herein a thermostat for controlling flow of a coolant fluid through an aperture, the thermostat comprising a temperature sensitive valve for controlling the opening and closing of the aperture, said temperature sensitive valve comprising: a valve body comprising a heat sensitive material and a displaceable pin; wherein said displaceable pin is at least partially inserted within said heat sensitive material; a lid configured to delimit the temperature sensitive valve from a top end thereof, said lid configured to seal against a valve seat when said temperature sensitive valve is closed; a support member configured to delimit the temperature sensitive valve from a bottom end thereof; and a flexible member located between said lid and said support member, wherein when said heat sensitive material is heated said displaceable pin is at least partially displaced from said valve body, thereby affecting a compression force on said flexible member, said compression force gradually displacing said tem

Abstract: The present invention provides a hydro-actuator thermostat system for controlling a temperature of an engine. The hydro-actuated thermostat system includes a thermal responsive valve system configured to induce opening of a temperature responsive valve upon an increase of a temperature of a coolant fluid, and to induce closing of the temperature responsive valve upon a decrease of a temperature of the coolant fluid. The hydro-actuated thermostat system further includes a hydraulic actuator system controllable by a controller, wherein the hydraulic actuator is associated with a thermal responsive valve system and configured to induce opening and/or closing of the temperature responsive valve in response to an indication from the controller, the opening and/or closing of the temperature responsive valve may be performed by controlling a fluid flow to and/or from the hydraulic actuator.

Abstract: The hydraulic linear actuator system of the present invention includes a pump that is configured to rotate in a single direction at a substantially constant velocity. Both the direction and flow rate of fluid through the system is controlled by adjusting the positional relationship between the stator and the rotor of the pump. This positional relationship is adjustable between a forward flow state, a non-flow state and a reverse flow state. The hydraulic linear actuator is responsive to the flow of fluid through the system so as to be displaced in a first direction by the forward flow state of the pump and in a second direction by the reverse flow state of the pump.
