摘要： A pressure control valve for a fuel injection apparatus for internal combustion engines, including a housing with a high-pressure connection and a return connection and including a cup-shaped piston, which is disposed in a housing bore, can be moved axially between a valve seat oriented toward the high-pressure connection and a stop oriented toward the return connection, counter to the spring force of a spring acting in the direction of the valve seat, and has at least one through opening that connects the inside of the cup-shaped piston to the housing bore, is characterized in that at least one throttle element is disposed upstream and/or downstream of the valve seat in the flow direction of the fuel.
