Thermostatic valve for a fluid circulation circuit and internal combustion engine provided with a fluid circulation circuit comprising such a valve

摘要

The valve has a sleeve (22) to control fluid passage between coolant circulation openings. A thermostatic unit (40) has a piston (44) moving with respect to a body (42). The sleeve is mounted on the piston such that relative movement between the sleeve and a sleeve support seat is controlled by a relative movement between the piston and body. A valve bridge (56) drives the body in a direction of displacement of the piston. An independent claim is also included for a thermal engine associated with a coolant circulation circuit.
