Valve with a direct passage and rotary control

A valve having a direct passage and rotary control, comprising:

• a body including an orifice therethrough;
• a cover adapted to sealingly engage said body and including an orifice therethrough and positioned such that when said cover is sealingly engaged with said body said orifice of said cover is axially aligned with said orifice of said body;
• a first plate rotatably disposed in said body near a bottom of said body and including an orifice therethrough such that when said valve is in a valve open position for a fluid flow therethrough said orifice of said first plate is axially aligned with said orifice of said body, and when said valve is in a valve closed position said orifice of said first plate is out of alignment with said orifice of said body and said fluid flow is precluded frrom passing through said valve;
• a lug integral with said first plate;
• a second plate rotatably disposed between said first plate and said cover and including an orifice and a lug hole therethrough, said lug hole adapted to receive said lug therein to align said orifice of said second plate with said orifice of said first plate and wherein said first plate and said second plate are rotatably disposed about a longitudinal axis of said valve;
• drive means operatively associated with said second plate for alternately rotating said second plate to said valve open position and said valve closed position, said drive means including a motor having a rotational axis parallel to said longitudinal axis and wherein said motor has a lateral dimension such that any peripheral edge of said motor does not extend beyond any peripheral edge of said valve;
• a stop member integral with said cover and positioned such that said lug abuts against said stop member when said valve is in said valve closed position;
• a ratchet mechanism operatively associated with said first plate and said second plate and disposed therebetween such that when said drive means alternately rotates said second plate to said valve open position and said valve closed position said ratchet mechanism is constructed so as to be operative to engage said first plate with said second plate during rotation thereof, and when said lug abuts against said stop member said ratchet mechanism is constructed so as to be operative to axially displace said first plate against said bottom of said body;
• and
• a sealing joint disposed about said orifice of said body such that when said first plate is axially displaced by said ratchet mechanism said sealing joint is compressed in a sealtight manner about said orifice of said body by said first plate and said fluid flow through said orifice of said body is precluded.
