Valve unit, especially for the crankcase of an internal combustion motor, has a heater to prevent it from freezing

摘要

The valve unit (12), especially for bleeding the crankcase of an internal combustion motor, has at least one fluid channel (26) and at least one heater (46) with a heat conductor (34) to heat the inner wall of the fluid channel. The valve body (18) has a valve seat (30,36) to close the fluid channel. When at rest, the valve body is against the seat so that it is directly or indirectly in contact with the heat conductor.
