Claims (1)
ラムと、該ダイヤフラムに密接′して該低圧室および高
圧室の差圧力を受けるダイヤフラムプレー１・を有する
パワーピストンとを備え、該パワーピストンが該差圧力
に応じてブレーキ操作力を助勢するブレーキブースタに
おいて、前記ダイヤフラムプレートの、前記ダイヤフラ
ムとの密接面に、その内周部から外周部に向い且つ前記
低圧室に通じる複数の溝を略放射状に形成し、該ダイヤ
プラムプレートとダイヤフラムとの間に挾まれた空気が
該複数の溝を通って確実且つ速やかに除去されるように
したことを特徴とするブレーキブースタ。The power piston is equipped with a diaphragm that airtightly divides the inside of the shell into a low pressure chamber and a high pressure chamber, and a power piston having a diaphragm plate 1 that is in close contact with the diaphragm and receives differential pressure between the low pressure chamber and the high pressure chamber. In this brake booster, the diaphragm plate has a plurality of grooves extending from its inner circumference to its outer circumference and communicating with the low pressure chamber on a surface of the diaphragm plate that is in close contact with the diaphragm. A brake booster characterized in that the brake booster is formed in a radial shape so that air trapped between the diaphragm plate and the diaphragm is reliably and quickly removed through the plurality of grooves.
