INJECTION DEVICE, CONTROL VALVE AND METHOD FOR INJECTING FLUID

摘要

The invention relates to an injection device comprising a fluid supply (10), a control valve (12), an actuator (14) which is used to impinge a force upon an area of a first front surface (24) of the control valve (12), and a control chamber (30) which is provided on the side of a second front surface (26). A compensation chamber (28) is provided on the side of the first front surface (24) of the control valve (12). The compensation chamber (28) is partially defined by the first front surface (24) of the control valve (12). The compensation chamber (28) communicates with the control chamber (30). The invention also relates to a control valve and a method for injecting fluid.
