Document Type and Number:
Japanese Patent JP2006161857
Kind Code:
A
Abstract:

To provide a booster with a cylinder having compact construction.

Boosting chambers 22a, 22b and pressurizing chambers 21a, 21b are formed in the cylinder by a hollow piston 18 and guide rods 16a, 16b incorporated in the cylinder 13. Primary side air is supplied from an input port 31 via a check valve into the boosting chambers 22a, 22b. Boosted secondary side air is discharged via the check valve to an output port 32. The primary side air is selectively supplied via a selector valve 35 to either one of the pressurizing chambers. When the piston 18 is moved to the end position of reciprocating motion, the pressurizing chamber to which the primary side air is supplied is switched by pilot pistons 49a, 49b.
