Provided is a thermostat device in which the direction of a radiator-side pipe can be easily changed and which can suppress cost. A housing includes a first housing member having a radiator-side pipe and a second housing member that is rotation-fastened to the first housing member by a bayonet structure. The bayonet structure has a plurality of claw parts that are formed side by side in a circumferential direction on one of the first and second housing members and a plurality of locking parts that are formed on the other of the first housing member and the second housing member and with which the claw parts engage. The radiator-side pipe, when seen from one side of a rotational axis X during the fastening of the first and second housing member, is inclined with respect to the rotational axis X.

A valve assembly for a faucet assembly includes a housing, a thermal motor and a sealing element. The housing includes a first inlet that receives water from a first source, a spout outlet in fluid connection with the first inlet, and a second inlet that receives water from a second source. The thermal motor is within the housing and imparts linear force in an axial direction. The sealing element is operably coupled to move in response to the imparted linear force, and is configured to engage a seating element to form a seal between the second inlet and the spout outlet. The seating element is disposed axially between the motor and the sealing element, and movement of the sealing element in the axial direction breaks the formed seal to allow fluid flow within the housing between the second inlet and the spout outlet.

A thermostat comprises a hollow body containing a thermally responsive material, and a force transmitting member affixed to the body by an over-molded portion.

A coolant control valve includes an actuator, at least one valve body, an outer housing, and a temperature sensor having a first flow state and a second flow state. The first and second flow states can be achieved by first and second axial positions of the temperature sensor.

A thermostat valve has a cylindrical valve housing formed as a single integrated unit out of synthetic resin material, having an annular body and a frame attached to one end of the annular body by a plurality of legs, a disk-shaped valve stem disposed in another end of the valve housing and movable along an axial direction, a spring seat that holds an opposite end of spring means away from the valve stem and locked and held in place by hooks at tips of locking arms extending from the valve housing, and a thermo-element fixedly mounted to an element guide provided in the frame of the valve housing that moves the valve stem in a valve opening direction in response to fluid temperature. An annular step having a top portion of predetermined width is formed adjacent to the rim of the opening in the one end of the valve housing.

A thermo valve is configured by coupling a valve body to a thermo actuator via a coupling part. The valve body has at least two recesses extending in a peripheral direction. The thermo actuator and the valve body overlap each other in a direction of an axial centerline to cover at least one of the recesses. The coupling part is formed by at least a certain section of the overlapping portion being depressed toward the axial centerline and another section of the thermo actuator fitting in the recesses. The depression of the coupling part has a shape elongated in a longitudinal direction along the axial centerline.

Provided herein is a valve with a housing, a thermostatic element of which a first end part of a piston, which axially opposes the end submerged in a thermodilatable material contained in the body of the thermostatic element, is secured to the housing; a return spring; an electrical heating resistance arranged inside the second end part of the piston; electrical connection for feeding the resistance from outside the housing; and a check mechanism for controlling a flow of fluid circulating through the housing, in a direction leading from the first end part towards the second end part of the piston, and connected to the body of the thermostatic element such that the relative movements between the body and the piston, resulting from the dilation and contraction of the thermodilatable material, move the check mechanism in relation to the housing, between closed and open positions affecting the flow of fluid.

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.

A first module includes a thermostatic element and a main seal. The main seal is, axially movable to open and close a main valve, and is linked to a movable part of the thermostatic element to open the main valve. A spring biases the movable part towards the fixed part of the thermostatic element, controlling the closing of the main valve. A bracket supporting the spring is interposed axially between the spring and a fixed casing. A cradle supports the first module, and removably inserts the first module therein, by axially interposing the cradle between the first module and the spring. The cradle includes a by-pass seal axially movable to open/close a by-pass valve when the main valve is opened/closed. The cradle is linked to the bracket in an axially movable manner, with the spring interposed axially and held fixedly to the bracket to keep the spring compressed.

A passive thermal control valve comprising a thermal actuator coupled to a valve body having first and second ports. The thermal actuator including an actuator body having an inner bore. An adjustment stop engages the actuator body. A cylinder is received within the actuator body inner bore and the cylinder has a cylinder bore open at one end. An actuator spring within the actuator body biases the cylinder towards the adjustment stop. An actuator rod is at least partially received within the cylinder and has first and second ends. At least a portion of the actuator rod is allowed to extend through the open cylinder bore. A sealing element forms a seal between the actuator rod and the cylinder and defines a sealed chamber within the cylinder. A thermal fluid is contained within the cylinder. A lever mechanism is connected to the valve body and includes a lever having a first end connected to the valve body. A valve spool is connected to a lever second end. The valve spool is arranged and designed to close the first port and allow a system fluid to flow through the second port, close the second port and allow the system fluid to flow through the first port, or allow the system fluid to flow through both the first and second ports.
