Abstract
A connection fitting (8) of a heat management module (1) of an internal combustion engine can be inserted into a receptacle hole (9) in a housing (2) of the heat management module. The aim is to be able to bias a sealing ring (16) of the nozzle against a rotary valve (3) using a compression spring element (13). The connection fitting is to be provided with a stop (24) that limits the longitudinal movement of the sealing ring in the direction of the rotary valve.
Claims17
A connection fitting of a heat management module of an internal combustion engine, said connection fitting being adapted to be inserted into a receptacle hole of a housing of the heat management module and comprising a sealing ring and a compression spring, the sealing ring includes a first axial end that is adapted to be biased against a rotary valve by the compression spring, the sealing ring includes a stop defined at a second axial end, opposite from the first axial end that limits a longitudinal movement of the sealing ring in a direction of the rotary valve, the sealing ring defining a cylindrical recess defined on a radially inner surface of the sealing ring in which a ring-shaped grooved ring is held, the ring-shaped groove ring including a sealing lip extending radially inward and contacting a hollow cylindrical fitting section of the connection fitting.
A connection fitting of a heat management module of an internal combustion engine, said connection fitting comprising:
- a fitting body that is insertable into a receptacle hole of a housing of the heat management module;
- a sealing ring that is movable in an axial direction relative to the fitting body, the sealing ring including a first axial end that is adapted to be biased against a rotary valve by a compression spring, and a second axial end, opposite from the first axial end that includes a stop that limits a longitudinal movement of the sealing ring in the axial direction, the sealing ring defining a cylindrical recess defined on a radially inner surface of the sealing ring in which a ring-shaped grooved ring is held, the ring-shaped groove ring including a sealing lip extending radially inward and contacting a hollow cylindrical fitting section of the connection fitting;
- and
- the compression spring biases the sealing ring in an axial direction away from the fitting body such that it is adapted to be pressed against the rotary valve of the heat management module.
