Abstract:
Injection device having an injection valve (12), a valve device (18, 20) for controlling the injection, and a settling element (22) for operating the valve device (18, 20), characterized in that the valve device has at least one first valve (18) and a second valve (20), which can be operated by the settling element (22) via a common hydraulic coupling space, wherein a pressure booster for intensifying a primary pressure is provided, which can be operated by the valve device (18, 29), wherein the first valve (18) in a first state separates the primary pressure from a low-pressure space (32) of the pressure booster (16), the first valve (18) in a second states injects the primary pressure in the low-pressure space (32) of the pressure booster (18), the second valve (20) in a first state couples a low-pressure space (32) of the pressure booster (16) with a leakage system (34), and the second valve (20) in a second state separates the low-pressure space (32) of the pressure booster (16) from the leakage system (34).
