Abstract

A pressure regulator (1) includes a housing (2) having a small-diameter flow passage (6) with an inflow port (9) and also having a large-diameter flow passage (5) with an outflow port (12). The small-diameter flow passage (6) and the large-diameter flow passage (5) are interconnected in the housing (2). An opening (8) of the small-diameter flow passage (6) is formed in the connection part between the small-diameter flow passage (6) and the large-diameter flow passage (5) so as to face the large-diameter flow passage (5). A ball (3) in contact with the peripheral edge (11) of the opening (8) is disposed in the large-diameter flow passage (5). The ball (3) is pressed against the peripheral edge (11) by a valve spring (4). The inner diameter (D1) of the large-diameter flow passage (5) is set such that the center of gravity (G) of the ball (3) is closer to the center of the opening (8) than the peripheral edge (11) with the ball (3) in contact with the inner peripheral wall (5a) of the large-diameter flow passage.
