Abstract:
A brake booster for a vehicle is provided. The booster includes a casing formed by a combination of a front and rear shell. A diaphragm divides the casing into a constant and a variable pressure room. A circumference of a front side end seals a valve body combined with the diaphragm and a rear portion penetrates the rear shell. A high pressure air passage selectively provides high pressure air from the rear portion to the variable pressure room and a bypass passage selectively provides atmospheric air to the variable pressure room. A check valve provides high pressure air passed a turbo charger and an intercooler to the variable pressure room through the high pressure air passage. An input rod advances and retreats through an air valve of the valve body. An output rod delivers force based on displacement of the air valve and the diaphragm to a master cylinder.

Claim (Index 1):
A brake booster for a vehicle, comprising:\n a casing formed by combination of a front shell and a rear shell; a diaphragm that divides an interior portion of the casing into a constant pressure room and a variable pressure room; a valve body sealed by a circumference of a front side end and combined with a center portion of the diaphragm and a rear portion that penetrates the rear shell, and having a high pressure air passage that selectively provides high pressure air from the rear portion to the variable pressure room and a bypass passage that selectively provides atmospheric air to the variable pressure room; a check valve connected with the high pressure air passage and configured to provide high pressure air passed a turbo charger and an intercooler to the variable pressure room through the high pressure air passage; an input rod of which a front side end is disposed to move to advance and retreat through an air valve disposed at a center portion of the valve body and a rear side end connected with a brake pedal; an output rod connected with a center portion of a front end portion of the valve body by interposing a reaction disk, and configured to deliver force based on displacement of the air valve and the diaphragm to a master cylinder; and an elastic member interposed between the front shell and the diaphragm to provide elastic force to the diaphragm.
