Abstract (en)

[origin: WO2004040119A1] The invention concerns an injection valve (1) comprising a valve-control module (2) and an injector module (3) which is connected to said valve-control module and includes an injector needle valve (12) axially mobile in an injector body (13) The valve-control module (2) is adjacent the injector module (3) with a throttle plate (14). An intermediate element is located in the zone of one end of the injector needle valve (12) facing the throttle plate (14). Said intermediate element is compressed on the throttle plate (14) by a spring (18) arranged between the intermediate element (21) and the injector needle valve (12) and said throttle plate biases the injector needle valve (12) in the closure direction with axial force. The inventive injection valve further comprises at least one outlet throttle (24) in the throttle plate (14) and at least one intake throttle (23) connected to a high pressure zone (9), said throttles emerging into a valve-control chamber (22). The throttle plate has on its side facing the injector module (3) a closed projecting portion (26) which defines an inner chamber (25), constituting a delimitation of the valve-control chamber (22) wherein is located the intake throttle (23).
