Power-plant, esp. for space vehicles and using liquid propellant

摘要

The power-plant works esp. using the catalytic or thermal decomposition of a liquid energy source. It has a propellant valve, which is upstream from an injector head which acts upon a reaction chamber. A spring-loaded one-way valve (10) is arranged between the propellant valve and the injector head, and opens automatically in the direction of flow. The one-way valve may have a valve plate (11) which has transmission holes (14), and which is acted upon by a spiral spring (12). The plate may also have a stop (26) on the side which faces away from the valve seat, in order to limit its stroke.
