<p>The invention can be used for releasing and locking fluid streams in all constant pressure systems, i.e. the systems having pressure before and after valve as, for example, cooling systems. The inventive valve system comprises a main distribution valve (7), a main valve chamber (25) arranged thereabove, primary (11) and secondary (13) fluid ducts, a fluid duct (26) connecting the primary fluid duct (11) to the main fluid chamber (25), a fluid duct (28) connected to an atmospheric pressure tank, a cylinder (2), solenoid (1), piston (3), spring (24) and two control valves (4, 5) which control the fluid ducts (27, 28), respectively.</p> |
