Abstract
A shutter valve for regulating pressure and controlling fluid flow comprising: an actuator ring comprising a plurality of gear teeth, the gear teeth driven by a mating gear; a plurality of arm pin bosses, each pin boss affixed within an inside circumference of the actuator ring, each arm pin boss further comprising a hinge pin aperture; three or more pivot arms, each pivot arm having a first end and a second end, the first end forming a hinge and mounted to a hinge pin aperture of an arm pin boss; three or more obturator elements; and a housing defining a cavity for holding the actuator ring, the pivot arms and the obturator elements.
Claims19
A shutter valve for regulating pressure and controlling fluid flow, comprising:
- an actuator ring, the actuator ring further comprising a plurality of gear teeth, the gear teeth driven by a mating gear;
- a plurality of arm pin bosses, each pin boss affixed within an inside circumference of the actuator ring, the arm pin boss further comprising a hinge pin aperture;
- three or more pivot arms, each pivot arm having a first end and a second end, the first end mounted to a hinge pin aperture of an arm pin boss;
- three or more obturator elements, each obturator element comprising:
- a) a petal shape structure including a tongue and groove feature along at least a portion of an outside circumference thereof;
- b) a hook element located at an apex of said petal shape structure of each obturator element;
- and
- c) a hinged connection to a second end of a pivot arm;
- and
- a housing defining a cavity for holding the actuator ring, the pivot arms and the obturator elements.
A shutter valve for regulating pressure and controlling fluid flow, comprising:
- an actuator ring, the actuator ring further comprising a plurality of gear teeth, the gear teeth driven by a mating gear;
- a plurality of arm pin bosses, each pin boss affixed within an inside circumference of the actuator ring, the arm pin boss further comprising a hinge pin aperture;
- three or more pivot arms, each pivot arm having a first end and a second end, the first end hingably mounted to a hinge pin aperture of an arm pin boss, such that rotational movement of the actuator ring causes movement of the pivot arms;
- three or more obturator elements, each obturator element comprising:
- a) a petal shape structure including a locking feature along at least a portion of an outside circumference thereof;
- b) a hook element located at an apex of said petal shape structure of each obturator element;
- c) a hinged connection to a second end of a pivot arm, such that movement of the pivot arm causes movement of the corresponding obturator element;
- and
- d) a hinged connection to a housing;
- and
- a housing defining a cavity for holding the actuator ring, the pivot arms and the obturator elements, further comprising a plurality of hinge pin apertures for coupling to hinged connections to obturator elements.

- d) a hinged connection to a housing;
- and
- a housing defining a cavity for holding the actuator ring, the pivot arms and the obturator elements, comprising:
- a) a plurality of hinge pin apertures for coupling to hinged connections to obturator elements;
- and
- b) a plurality of walled protrusions within said cavity, each walled protrusion providing a surface against which a primary surface of each obturator element slides when the obturator elements move.
