Abstract
There is disclosed herein a throttling valve of the axial flow type for controlling fluid flow. The valve includes an expandable sleeve of resilient material having a toroidal configuration and positioned within a housing on a cage member. When the sleeve is in a rest position there is no fluid flow, but the sleeve can expand as a result of differential pressure acting thereon to allow flow in varying degrees between the sleeve and cage.
