摘要:
A booster as may be used in a brake of an automobile is disclosed, which permits the generation of sounds during the suction stroke when pressure fluid is introduced into a variable pressure chamber to be reduced. The inner surface of a valve body, which defines the variable pressure passage is formed as an uneven surface. This improves the muffler effect without degrading the response of the booster.
