Abstract

The throttle control for fluids has a control cylinder containing a rotary piston which has a circumferential groove of increasing cross-section connected to an input channel. The cylinder has at least one outflow aperture limited by a control edge which forms a variable throttle cross-section with the circumferential groove. In the cylinder (1) is a channel (12) which is in communication with the circumferential groove (6), and extends almost to the control edge (10). The channel is formed by a groove (12) running on the outer circumference of the control cylinder (1).
