Abstract: A control valve for a brake booster (10) having a first member (160) with a first bore (166), a second member (200) located in the first bore (166) and having a second bore (202), a plunger (54,80) located in the second bore (202) and connected to an input member (12). A gear (500) fixed to the second member (200) with teeth (502, 504) that engage a first rack (400) retained in the first body (160) and a stationary rack (402) within the brake booster (10). A force applied to the input member (12) controls the development of a pressure differential that moves a wall (38, 44) during a brake application. Movement of the wall (38, 44) causes a rotative torque to be transmitted from the first rack (400) into teeth (502, 504) such that the gear (500) moves with respect to the second rack (402) and the second body (200) to separates from the first body (160) and as a result the travel of input member (12) is less than the travel of the wall (38, 44) during a brake application.

Abstract translation: 一种用于制动助力器（10）的控制阀，具有具有第一孔（166）的第一构件（160），位于第一孔（166）中的第二构件（200），并具有第二孔（202） （54,80），其位于所述第二孔（202）中并且连接到输入构件（12）。 固定到第二构件（200）的齿轮（500）具有接合保持在第一主体（160）中的第一齿条（400）的齿（502,504）和制动助力器（10）内的固定齿条（402） 。 施加到输入构件（12）的力控制在制动施加期间移动壁（38,44）的压力差的发展。 壁（38,44）的移动导致旋转扭矩从第一齿条（400）传递到齿（502,504），使得齿轮（500）相对于第二齿条（402）移动，第二齿条 主体（200）与第一主体（160）分离，因此输入构件（12）的行程小于在制动施加期间壁（38,44）的行程。
