GAS PRESSURE REGULATOR Russian patent published in 1997 - IPC

FIELD: automatic control equipment for mechanical engineering. SUBSTANCE: device has housing 1, high pressure chamber 2, input channel 3, low pressure chamber 4, central channel 5, output channel 7, push 6, control constrictor 8, which is designed as saddle 9 and locking member 10 which is spring-loaded to saddle 9 by means of elastic member 11. In addition device has dampening chamber 12, which is spaced from low pressure chamber 4 with housing wall 13 which has connection hole 14 which is coaxial to central channel 5 and connects low pressure chamber 4 and dampening chamber 12. Sensitive member 15 is designed as diaphragm 16 which is mounted in housing and interacts with setting member 17. Pusher 6 connects sensitive member 15 to locking member 10 and runs through connection hole 14 in housing wall 13 with space. Cross section of pusher in region of central channel 5 is decreased in direction towards locking member 10. Input to output channel 7 is adjacent to input to connection hole 14. High pressure chamber 2 and control constrictor 8 are located in supply union 20. Sensitive member 15 may be designed as diaphragms 16 which are separated with sealed dampening chamber 26. EFFECT: increased precision and stability of control, simplified design, decreased metal usage, increased reliability of control due to optimal configuration, dampening and ejection without additional members. 10 cl, 3 dwg
