TH24912B - Low pressure booster device - Google Patents

Abstract

The DC60 low-pressure power booster, as described in this invention, shall have a thrust mechanism 24 situated between the cylinder of valve 10, the piston of valve 18, and the output rod 25. The thrust mechanism 24 shall consist of a flexible piston 22 positioned between the cylinder of valve 10 and the output rod 25; a thrust piston 17 orbiting toward the flexible piston 22 on the opposite side of the output rod 25 and having a smaller diameter than the flexible piston 22; and spring 48 situated between the thrust piston 17 and the piston of valve 18, providing a set force in the extension/retraction direction. Within the cylinder of valve 10, there shall be a stop 45 to brace the front end of the piston of valve 18 before spring 48 reaches its extension/retraction limit. The low-pressure booster device described in this invention shall have a thrust mechanism 24 located between the cylinder of valve 10, the piston of valve 18, and the output rod 25. The thrust mechanism 24 shall consist of a flexible piston 22 positioned between the cylinder of valve 10 and the output rod 25; a thrust piston 17 orbiting toward the flexible piston 22 on the opposite side of the output rod 25 and having a smaller diameter than the flexible piston 22; and a spring 48 positioned between the thrust piston 17 and the piston of valve 18, providing a set force in the extension/retraction direction. Within the cylinder of valve 10, there shall be a stop 45 to brace the front end of the piston of valve 18 before spring 48 reaches its extension/retraction limit.
