BAROSTATIC DOUBLE ACTING CONTROL VALVE Russian patent published in 2016 - IPC F02C7/00 F16K11/10 F16K17/04 

FIELD: motors and pumps.

SUBSTANCE: invention relates to a gas turbine engine system elements (CCD), and can be used in the lubrication system of heat-air turbine engines to control the pressure of the compressed air and the hot gases in the venting system. Barostatic double-acting valve for venting system aircraft gas turbine engine includes a housing with formed therein seats interacting with two poppet valves connected in parallel in the pipe venting, one of which - barostatic - is connected to the sensor, perceiving the change in pressure surrounding the engine atmosphere and the other valve - limiting the pressure in the venting system. Saddles are rotated in the same direction toward the sensing element, a pressure limiting valve is located between the sensing element and barostatic valve and mechanically coupled to the latter with the possibility of free running of both valves. Progress barostatic valve is greater than the valve travel limiting pressure.

EFFECT: present invention reduces the hydraulic resistance barostatic valve by increasing the flow section in the output path of the device that, according to the applicant, will increase the reliability of its work.
