Abstract
A device for sealing a valve for controlling a coolant of an internal combustion engine of a motor vehicle is described, which valve is mounted in a cooling system together with a valve housing, wherein the valve housing contains, at the inlet and/or the outlet side, a sealing ring which has an annular wall and a spaced annular lip extending away from the annular wall from a contact point.
Claims16
A device for sealing a valve, comprising:
- a cooling system disposed about an axis and having an annular inside wall and an annular outside wall spaced radially outwardly from the annular inside wall and defining an annular recess radially between the annular inside and annular outside walls;
- a sealing ring positioned about the axis and having an annular wall partially received in the annular recess of the cooling system and partially extending outside of the annular recess and positioned adjacent to the annular outside wall of the cooling system, and having a spaced annular lip at least partially received in the annular recess and extending axially and tapering radially inwardly away from the annular wall to a contact point and engaging the annular inside wall;
- wherein the sealing ring is positioned at an inlet side and/or an outlet side of a valve housing;
- wherein the annular wall of the sealing ring generally has a tubular shape and extends axially from a distal end received in the annular recess to a contact face for sealingly engaging the valve housing;
- and
- the contact face of the annular wall positioned entirely radially inwardly of the distal end of the annular wall and defining an outer shoulder between the contact face and the distal end along a radial outer surface of the annular wall and defining an inner shoulder along a radially inner surface of the annular wall such that a pressure against the outer shoulder biases the inner shoulder against the annular inside wall of the cooling system to seal the annular wall against the cooling system.

- the annular wall of the sealing ring extending axially from a contact face for sealingly engaging a valve housing to a distal end in the annular recess of the cooling system;
- and
- a spring positioned in the annular recess of the cooling system and biasing the distal end of the sealing ring toward the valve housing;
- the contact face of the annular wall positioned entirely radially inwardly of the distal end of the annular wall and defining an outer shoulder between the contact face and the distal end along a radial outer surface of the annular wall and defining an inner shoulder along a radially inner surface of the annular wall such that a pressure against the outer shoulder biases the inner shoulder against the annular inside wall of the cooling system to seal the annular wall against the cooling system.

- a sealing ring having an annular wall extending axially between a distal end received in the annular recess of the cooling system and a contact face for axially engaging a valve housing;
- the sealing ring further including an annular lip extending axially and radially inwardly from the annular wall from a contact point and radially engaging the annular inside wall of the cooling system inside the annular recess;
- the sealing ring defining an annular channel between the annular wall and the sealing ring annular lip such that pressure within the annular channel biases the annular lip radially against the annular inside wall of the cooling system and biases the contact face axially against the valve housing;
- the contact face of the annular wall positioned entirely radially inwardly of the distal end of the annular wall and defining an outer shoulder between the contact face and the distal end along a radial outer surface of the annular wall and defining an inner shoulder along a radially inner surface of the annular wall such that a pressure against the outer shoulder biases the inner shoulder against the annular inside wall of the cooling system to seal the annular wall against the cooling system.
