Apparatus for flow rate control
First Claim
1. An apparatus to control the flow rate of a fluid, comprising:
- a first clamp body having a channel with a shape curved in a direction along a length of the channel and with a depth that varies as a predetermined function of angular position along the length of the channel;
a second clamp body coupled to said first clamp body; and
a clamping structure coupled to at least one of said first and second clamp bodies, movably disposed in the channel.

Abstract
A clamp having a first clamp body, a second clamp body, and a clamping structure coupled to at least one of the first and second clamp bodies. One or both of the clamp bodies form a channel adapted to receive a tube. The clamping structure is movable in the channel to control the flow rate of a fluid flowing through the tube. In one embodiment, the clamp is provided as a rotary clamp having clamp bodies that are adapted to be rotated relative to each other to control the flow rate of a fluid through a tube disposed in the rotary clamp. The rotary clamp has a substantially linear, or otherwise pre-determined, relationship between flow rate of a fluid flowing through the tube and rotation of the second clamp body.
