A choke valve, whose choke body comprises a cylindrical choke position plunging coaxially into an inlet duct. The inlet flow duct is connected on the one hand with an inlet and on the other hand communicates through transfer openings with outlet flow ducts extending through the wall of the flow duct, such outlet flow ducts begin connected with the outlet. Between the choke piston and the inlet flow duct wall a seal area is provided, which on resetting the choke body is shifted axially and, cooperating with the transfer apertures, sets the aperture for the pressure medium.
