Sealing device for a piston rod of a stirling engine |
摘要 |
The present invention relates to a sealing device provided between a piston rod of a Stirling cycle engine and a variable volume chamber. The sealing device is provided with an arrangement so as to equalize pressures between a seal chamber and the variable volume chamber of the Stirling cycle engine. By equalizing pressures between the respective spaces, an overpressure is prevented which would otherwise distort the seal and permit oil to be carried into the working volume of the Stirling cycle engine.
