Reserve circuit for liquid gas-powered vehicle has reserve tank enclosed by thermal insulation whose dimensions are selected so liquid gas in reserve tank is limited to simmering so liquid gas storage space is maintained in reserve tank

摘要

The circuit has a non-return valve that limits the passage of a reserve gas output line (2) and that is controlled by an empty state sensor (3) and at least one reserve tank (5) enclosed by a thermal insulation material (7) whose dimensions are selected so that the liquid gas in the reserve tank is limited to simmering so a liquid gas storage space (17) is maintained in the reserve tank.
