ABSTRACT:
Structure and method are disclosed for providing timed valving in which a nutating plate having an opening defined therethrough moves relative to at least one other nominally static plate having a complementary opening defined therethrough, the nutating plate at one portion of the nutating travel bringing the opening defined therethrough in alignment with the complementary static opening and in another portion of the nutating movement positioning such opening therethrough in a spaced, sealing relationship relative to the complementary static opening. Either the nutating or nominally static plate may be utilized in pairs such that a sandwiched relationship between one type of plate and the other exists. The walls of the opening in the static plate are angularly disposed with respect to the walls of the opening defined in the nutating plate and steadily converge in the direction toward the nutating plate thereby restricting the opening in the static plate at the face adjacent to the nutating plate, with the angular disposition and convergence being configured to reduce turbulent flow during opening and closing of the valving structure. Timing of the opening and closing of the valving structure may be adjusted relative to the drive shaft so as to provide opening and closing cycles of selected portions of an entire rotation.
