FIELD: test equipment. SUBSTANCE: spaceship has a compartment with pneumo-hydraulic systems, whose units and pipelines are positioned both inside and outside the compartment. The device uses a vacuum chamber used to accommodate the spaceship to be checked and a leakage detector installed on the vacuum chamber, and three valves connected to the leakage measuring unit made as a measuring reservoir with adjustable test leakage and pressure pickup installed in it; two pipelines installed in the vacuum chamber are connected with their one end through the passage members of the vacuum chamber to the respective valves, the other end of the first pipeline is connected to the compartment interior, and the other end of the second pipeline is freely attached in the zone of communication of the compartment interior with the vacuum chamber. The pipelines and valves have the same lengths, flow areas, hydraulic resistances. EFFECT: enhanced accuracy. 1 dwg
