Abstract:
My invention comprises a novel combination of devices wherewith the disks of a straightway valve can be forced away from each other when closed or thrown wide open. When closed, said disks are forced tightly against their respective seats, so as to completely obstruct the channels or fluid pas- sages, but when opened, said disks then bear against the walls of the valve-chamber proper.
Claim:
The combination, in a straightway valve, of a shell having a pair of channels; a chamber provided with a pair of guides and two valve-seats; a vibrating lever whose free end swings within said chamber and has an integral longitudinal-wedge, with its thin end presented toward the axis of said lever; a carrier, perforated on its opposite sides, and adapted to slide freely along said lever; and a pair of valves having pivots inserted within said perforations; the arrangement of these devices being such as to confine said valves to a recti-lineal path within said guide, when the free end of said lever describes an arc of a circle, and to gradually force said valves away from each other as the lever approaches the terminations of its stroke, at which time the thicker portion of said wedge bears against said pivots. |
