Control valve
First Claim
1. A control valve for controlling the flow of fluent material from a machine having a frame including a hopper and a tube mounted to the hopper, the machine also having a hose mounted to the tube, the control valve comprising:
- (a) a clamp having a first arm mounted to the frame on a first side of said hose and a second arm mounted to the frame on an opposite side of said hose, wherein at least the first arm is movably mounted to the frame; and
(b) at least one prime mover drivingly linked to the first arm and the frame for displacing the first arm toward the hose, thereby clamping the hose between the first and second arms for restricting the flow of fluent material through the hose.

Abstract
A control valve for controlling the flow of fluent material from a machine, the machine having a frame including a hopper and a tube mounted to the hopper, an auger within the tube and a hose mounted to the tube. The control valve has a clamp, which has a first arm mounted to the frame on a first side of the hose and a second arm mounted to the frame on an opposite side of the hose. The first arm is movably mounted to the frame in a direction toward the hose. A prime mover is drivingly linked to the first arm and the frame for displacing the first arm toward the hose, thereby clamping the hose between the first and second arms for restricting the flow of fluent material through the hose.

15. A control valve for controlling the flow of fluent material from a machine having a frame including a hopper and a tube mounted to the hopper, the machine also including an auger within the tube and a hose mounted to the tube, the control valve comprising:
-
(a) a clamp having a first arm pivotably connected to the tube near a first side of said hose and a second arm pivotably connected to the tube near an opposite side of said hose, wherein the first arm is drivingly linked to the second arm by intermeshing gears on each of the arms for movement of the arms from an open position to a flow restricting position; and
(b) a prime mover pivotably mounted to the first arm near a first prime mover end and mounted to the frame near a second prime mover end for displacing the arms toward the hose. - View Dependent Claims (16, 17, 18, 19, 20)
