METHOD FOR CONTROL OF COMPRESSOR UNIT AND COMPRESSOR UNIT Russian patent published in 2012 - IPC F16T1/00 

FIELD: machine building.

SUBSTANCE: method includes a stage of control, at least over one of drain valves on the basis of at least one system parameter, at the side of the drain valve supply, at the same time the method includes the following stages: detection of pressure on the side of supply of appropriate drain valves and control of other drain valves, besides, two drain valves having different pressure values at the supply side, may not be open simultaneously; or control of two drain valves arranged in the form of a part of a compressor unit, besides, they may never be in an open condition simultaneously. The compressor unit is equipped with at least two drain valves, which are connected to the control device, which is connected with a detecting device for detection of at least one parameter of the system, which is not a parameter of the system on the side of supply of one of drain valves, and at the same time the control device includes a logic for control of at least one of drain valves on the basis of a certain parameter of the system.

EFFECT: simplification of design.
