DIRECT ACTION TEMPERATURE CONTROL Russian patent published in 1994 - IPC

FIELD: temperature control equipment. SUBSTANCE: direct action temperature control has case; there is a temperature-sensitive element in space of the case. The element is formed by movable cup in longitudinal channels of which two groups of movable rods are disposed. The rods act on valve unit of the control to increase or to reduce flow section of the control. Dilatometric effect of temperature-sensitive element is used in the control. After being multiple multiplied on levers which have the different lengths of arms, the dilatometric effect influences onto valve unit and increases or reduces flow section of the temperature control. EFFECT: simplified design; improved reliability; reduced labour input. 4 dwg
