Abstract (en)
[origin: EP1413742A1] The device has a housing with an injection region, an aperture with two coaxial valve elements and valve seats, an actuating device that opens the shorter inner valve element, a control piston with a pressure surface with resultant force in the closing direction bounding a control chamber. The actuating device exerts an approximately constant opening force on the inner element. The fluid pressure in the control chamber can temporarily reduce. The device has a housing with an injection region, an aperture (44) with two coaxial valve elements (46,48) that interact with valve seats (52,56) in the injection region, an actuating device that opens the shorter inner valve element at least at times, a control piston (92) interacting with the inner element with a pressure surface whose resultant force acts in the closing direction and bounds a control chamber (104). The actuating device exerts an approximately constant opening force on the inner element and a fluid pressure occurs in the control chamber that can temporarily reduce.
