The sealing ring has a radially inwardly directed, circularly running sealing ring inner side with three tangential cuts separating three sealing ring segments are arranged in a circumferential direction (U). The base and sealing rings are arranged in succession in a longitudinal direction (L). A top ring is arranged to adjoin the sealing ring having a top ring has a radially outwardly directed top ring outer side and a radially inwardly directed top ring inner side. The top ring has, on the side opposite the sealing ring, a radially running return flow channel extending radially, the sealing face side protrudes in a radial direction beyond the top ring outer side and the base ring face side. The base and the top rings have a greater tensile strength than the sealing ring.

摘要： Fuel gas supply system for supplying a high-pressure gas injection engine with gas stored in a liquefied gas tank, preferably an LNG tank, having a high-pressure pump to which liquefied gas is supplied. The system including a condenser with a high-pressure heat exchanger, a high-pressure vaporizer which is connected to the high-pressure pump via the high-pressure heat exchanger and is arranged downstream of the condenser. Gas fed to the high-pressure gas injection engine downstream of the high-pressure evaporator. A compressor to which boil-off gas is fed is connected downstream to the condenser via an inlet. A condensation core generator to which liquid gas is supplied from the high-pressure pump in such a manner that the condensation nuclei generated by the condensation nucleus generator promote condensation of the supplied boil-off gas. The liquid gas formed in the condenser is supplied to the high-pressure pump and/or to the liquid gas tank.
