Method of sealing the rod of a piston moving to and fro, especially in Stirling engines, and the device for sealing the rod of a piston moving to and fro, especially in the Stirling engine.

摘要

1. The method of sealing the rod of a piston moving to and fro, especially in Stirling engines, consists in implementing mechanical sealing in the form of a gland equipped with sealing rings, skimming rings and a cooling system. Unique characteristics: Lubricating oil solvent is pumped into the gland chamber through the inflow duct (11) into the tank (8) during engine operation. The piston rod is bathed in the oil solvent in the tank. The used oil solvent is carried outside the engine by means of the outflow duct (14). Simultaneously, the piston rod (2) is heated with the heat radiation emitter (17), located in the chamber (15) of the gland (1), up to the oil boiling point and the oil is evaporated from the rod surface. Then... 5. The device for sealing the rod of a piston moving to and fro, especially in Stirling engines, consists of a gland equipped with sealing and skimming rings and a cooling system. Unique characteristics: The housing of the gland (1) contains the ring-shaped flow tank (8) of oil solvent, which the piston rod (2) passes through. The tank (8) is connected to the solvent inflow duct (11) and to the outflow duct (14) for the used oil solvent, which...
