VIBRATION DAMPER FOR FLUID MEDIUM CONTROL DEVICE Russian patent published in 2010 - IPC G05D16/02 

FIELD: physics.

SUBSTANCE: fluid medium control device has a housing, a piston, having an outer lateral surface and configured to react on pressure inside the housing, a guide ring linked to the housing and having an hole configured for allowing entrance of at least part of the piston, a vibration damper between the guide ring and the piston in order to provide frictional contact for the outer lateral surface of the piston without acting on the vibration damper during operation of the fluid medium. The vibration damper has a spring-loading component which is at least partially surrounded by a shell made from some material. The vibration damper has a guide ring. The guide ring has an inner and outer lateral surface, a flange coming out of the outer lateral surface, a support element integrated with the inner lateral surface and configured to hold the deformed ring in frictional contact with the piston. The vibration damper is configured in such a way that it is not acted up by the fluid medium during operation. The deformed ring also has a spring-loading component and provides the frictional coefficient of the piston.

EFFECT: reduced undesirable fluctuations or instability of the component regulating flow, and obtaining constant pressure at the output independent of such fluctuations.
