FIELD: machine building.SUBSTANCE: controlled throttle comprises a body, where a straight element is installed with a piston and a throttling unit, includes a seat, a bushing with throttling holes and with a ball stop element arranged as capable of changing the total throughput section of throttling holes during displacement of the ball stop element along the bushing with closure of throttling holes with the ball stop element, the travel of the ball stop element along the bushing is limited with the piston. Throttling holes may be arranged as triangular. The area of the throughput section of the seat is more than the total area of the throughput section of throttling holes.EFFECT: higher reliability and service life of a controlled throttle and a throttling unit.12 cl, 4 dwg |
