VALVE FOR ADJUSTMENT OF COOLING MEDIUM FLOW FOR COOLING PISTONS Russian patent published in 2022 - IPC F01M1/08 F01M1/16 F01P7/14 F01P3/08 

FIELD: mechanical engineering.

SUBSTANCE: throttle valve for adjustment of a cooling medium flow from a cooling medium source to a group of nozzles for cooling a group of pistons of an internal combustion engine includes channel (30) connecting the cooling medium source to the group of nozzles. Valve element (32) is made with the possibility of movement in channel (30) to the first position, in which valve element (32) does not impact on the flow cross-section. Valve element (32) contains control surface (42), on which a cooling medium impacts for movement of valve element (32). The implementation of control surface (42) and supplying channel (38) is disclosed. Valve element (32) is made with the possibility of movement between the first position and the second position, in which the flow cross-section is minimal or zero, while the second position is limited by stop (50) of valve element (32). A device for cooling a group of pistons, and a vehicle are also disclosed.

EFFECT: increase in the simplicity of a structure.
