Patent ID: 7040344

Claim:
A pressure regulator comprising: a housing including an inlet and an outlet; a divider separating the housing into a first chamber and a second chamber; a valve including a spherical valve ball and a seat, the spherical valve ball being fixed with respect to a first one of the housing and the divider, and the seat being fixed with respect to a second one of the housing and the divider, a first configuration of the spherical valve ball with respect to the seat substantially prevents fluid communication between the inlet and the outlet, and a second configuration of the spherical valve ball with respect to the seat permits fluid communication between the inlet and the outlet; a pocket receiving a portion of the spherical valve ball, the pocket being defined by a set of surfaces, the set of surfaces including a cylindrical surface coupled to an end surface, the cylindrical surface surrounding a longitudinal axis, and the end surface extending generally orthogonal relative to the longitudinal axis, wherein the spherical valve ball is fixed to the end surface.
