The thermostatic valve (1) comprises a thermostatic element (20) of which the moving part (22) brings about the movement, with respect to the valve body (10), of a shut-off element (30) that regulates the flow of a fluid through this valve body, and a compressed spring (40) designed to return this moving part towards the fixed part (21) of the thermostatic element and the relaxation force of which is borne by at least two arms (15) of the valve body, a first longitudinal end (152) of which is moulded as one with the remainder of this valve body. To make it easier to manufacture the valve body and to assemble it with the other components of the valve, each arm, at its second longitudinal end (15-i), delimits a contact surface (15A) for contact with the spring and against which surface one end (41) of this spring presses under of the effect of its relaxation. In addition, at its first end, each arm is connected to the rest of the valve body in a way that is deformable between a first extreme position in which the contact surface is positioned in line with the spring, and a second extreme position in which the contact surface is off-axis, passing through an intermediate position somewhere between these extreme positions, which intermediate position is occupied by the arm at rest and in which the contact surface (15A) of this arm is situated a radial distance (da) away from the axis (X-X) of the thermostatic element, which distance is less than the corresponding maximum radial dimension (d40) of the spring (40). |
