A thermostatic device including a thermostatic element and a stopper, axially movable about a stationary seat of a housing, opening and closing a passage circulating fluid and connected to a movable portion of the thermostatic element. During expansion of a thermoexpansible material of the thermostatic element, the movable portion drives the stopper axially relative to the seat. The stopper includes a seal, resting tightly against the seal when the fluid circulation passage is closed by the stopper, a first part, with an inner bore receiving the movable portion, and a second part, separate from the first part, the seal being axially charged between the first and second parts. The first and second parts are made of metal, the second part is mounted around the first part, the part facing the axis of the second part forms a peripheral edge attaching said second part to the outer surface of the first part, and the first part forms an axial abutment for the edge of the second part, positioning the first and second parts axially relative to one another by applying a predetermined clamping load to the seal.

A thermally actuated heat pipe control valve which includes a housing having a first opening for receiving a condenser portion of a heat pipe therein, a second opening for receiving an evaporator portion of the heat pipe therein and a passage extending through the housing from the first opening to the second opening. The passage is configured to receive working fluid from the heat pipe therein. A passage closing member is positioned in the housing proximate to or in the passage. The passage closing member having a surface which cooperates with a wall of the passage. At a specific temperature, the passage closing member moves into the passage to a closed position, preventing the flow of the working fluid, thereby preventing heat transfer between the condenser portion and the evaporator portion when the design temperature is reached or exceeded.

A thermostatic valve for a cooling system of an engine of a motor vehicle, having a thermostatic valve housing, on which a connection to a cylinder head of the engine, a connection to the engine block, a connection to a cooler of the cooling system and at least one connection to a bypass channel are designed, wherein a movable thermostatic operating element, a cooler valve, an engine block valve and a slide for closing the bypass channel are arranged in the thermostatic valve housing. The thermostatic valve has a first slide section is provided for closing a first opening arranged on the thermostatic valve housing and at least one second slide section for closing at least one second opening arranged on the thermostatic valve housing.

A mixing unit with a mixer tap for mixing two fluids and a method for manufacturing the mixer tap for mixing fluids are disclosed. The mixing unit has a cartridge, which is provided with a coupling base having an inlet for a first inflow, an inlet for a second inflow, and an outlet for an outflow obtained by mixing the inflows. The mixing unit also has a housing designed to be placed in a coupled position with the coupling base. The housing is designed to change the rate of the first inflow and/or second inflow on the basis of the temperature of the outflow. The mixing unit also includes an attachment for attaching additional housing to the coupling base. The attachment allows for movement of the additional housing, in relation to the cartridge, between the coupled position and a separated position.

A passive flow modulation device according to an embodiment includes: a pressure sensitive main valve controlling a flow of a cooling fluid from a first area to a second area through an orifice; and a temperature sensitive pilot valve coupled to the pressure sensitive main valve, the temperature sensitive pilot valve configured to open at a predetermined temperature in the first area, causing a pressurization of the pressure sensitive main valve, wherein the pressurization of the pressure sensitive main valve actuates the pressure sensitive main valve to an open position, allowing the cooling fluid to flow from the first area to the second area through the orifice.

A thermostat includes a carrier element which can be anchored in a housing, and a valve element which is movable relative to the carrier element. The valve element contacts the carrier element in a first position, whereby a duct within the housing can be closed. In a second position, which differs from the first position, the valve element does not contact the carrier element, whereby the duct can be opened. A wax element is arranged on the carrier element and is mechanically connected to the valve element. The wax element is configured to generate a stroke in case of a temperature change, by which the valve element can be moved.

A control valve for adjusting fluid flow has a cylindrical housing bushing with a first and a second flow opening. A control bushing is arranged coaxially in the housing bushing and adjustable between control positions opening and/or closing the flow openings. A first spacer disk and a second spacer disk are arranged axially spaced apart at the housing bushing and surround the housing bushing. At least the first spacer disk is arranged eccentrically at the housing bushing by eccentric displacement relative to a longitudinal axis of the control valve. A first side of the housing bushing has a larger radial spacing relative to an outer rim of the first spacer disk than a second side of the housing bushing. At least one of the first and second flow openings is arranged at the first side of the housing bushing. A cooling system is provided with such a control valve.

A thermostatic bypass valve has an intentional flow resistance through a bypass passageway when fluid is at a normal operating temperature. This flow resistance, of between 10 and 20 psi at a flow rate of 10 liters per minute, is achieved by limiting a radial clearance within the bypass passageway to less than 1.0 mm. The flow rate through the bypass passageway is at least half of the flow resistance of the cooler. This bypass flow resistance is beneficial because it limits the flow rate of lubrication fluid during bypass, reducing the parasitic losses of the gearbox.

A thermal valve for controlling a flow of fluid includes a housing having an inlet and an outlet configured to permit the flow of fluid through an interior of the housing, an actuator including heat-sensitive material configured to contract or expand based on a temperature of the fluid, a rod fixedly coupled to the housing and partially inside the actuator, the rod being configured to move relative to the actuator as the heat-sensitive material contracts or expands, a chamber inside the housing and fixedly coupled to the housing, the chamber being configured to accommodate the actuator, a first compressive resilient element configured to movably couple the actuator to the chamber, and a disc movably coupled to the chamber via a second compression element, and configured to permit flow of the fluid from the inlet to the outlet and to reduce flow of water from the outlet to the inlet.
