ABSTRACT:
A flow regulator for use in medical apparatus for adjusting the flow of fluid in which there is a valve body with a valve member having a helical flow passage through which the fluid must flow. In order to facilitate quick adjustment of the fluid, the pitch and depth of the groove both progressively change from one end of the flow regulating device to the other, the depth of the groove becoming less as the pitch of the groove becomes finer. The valve member is longitudinally movable with respect to the valve body, and provision is made for adjusting the longitudinal position either by rotation of a threaded valve stem or by longitudinal movement of the valve stem to quickly adjust the flow rate. The helical groove may be either rectangular in cross-section, or V-shaped in cross-section. Suitable means are provided for sealing against leakage through the valve adjusting means.
