System for supplying a consumer with gaseous fuel and associated method

摘要

The invention relates to a system for supplying a consumer with gaseous fuel. Said system comprises at least one compressed gas container, which is fluidically connected to the consumer via a collecting line and valves. To extensively utilise the capacity of the compressed gas container, a reserve container (3) is connected to the collecting line (12) via a first valve (9) and the system is equipped with an ejector pump (14), which is operated by gas from the reserve container (3) and delivers gas from the compressed gas container(s) (1, 2, . . . ) into the collecting line (12). To achieve this, with respect to the flow, the ejector pump (14) is situated between the compressed gas container(s) (1,2, . . . ) and the consumer (5).

主权项

1. A system for supplying a consumer with gaseous fuel, with at least one compressed gas container which is connected in terms of flow to the consumer via a collecting line and valves, wherein a reserve container is connected to the collecting line via a first valve, and wherein an ejector pump is provided, the ejector pump being operated with gas from the reserve container and feeding gas from the at least one compressed gas container into the collecting line, for which purpose the ejector pump is arranged, with regard to the flow, between the at least one compressed gas container and the consumer, and wherein a nonreturn valve is arranged in the collecting line between the at least one compressed gas container and the location where the gas coming from the reserve container opens out, said nonreturn valve preventing flow from the reserve container to the at least one compressed gas container.
