COMPENSATOR OF HYDRO-BLOW FOR FUEL METERS IN TRANSPORTATION MEANS (VARIANTS)

摘要

The group of inventions relates to suppression of pulsations in liquids or gases, in particular in counters of fuel systems of engines of vehicles. Compensators of hydro-blow have central pipeline surrounded with damping chamber. This is arranged as cylindrical rigid body with larger diameter. Circular space between this one and central pipeline is separated with cylindrical branch pipe into two cavities filled with inserts made of springy material. Ends of cylindrical branch pipe are closed with perforated covers diameters of which are equal to inner diameter of damping chamber. At the middle of central pipeline plug is installed for change of direction of motion of working medium. In the other variant of compensator the plug is installed on output end of central pipeline in which radial openings are provided for outlet of working medium to compensation chamber. Due to increase of length of pass of working medium in damping chamber effectiveness of suppression of hydro-blow is increased.
