Abstract
An injection device for injecting a medium, including a valve arrangement with a valve member forming a seal at a valve seat, wherein the valve arrangement is arranged in the medium to be injected, an actuator device with an actuator, a plunger and a return element, and a pulse-transmitting device which is arranged between the valve arrangement and the actuator device, which separates the valve arrangement from the actuator device in a fluid-tight manner and which transmits a pulse generated by the actuator device to the medium to be injected in order in that manner to open the valve arrangement and inject medium.
Claims14
An injection device for injecting a medium, comprising:
- a valve arrangement having a valve member forming a seal at a valve seat, wherein the valve arrangement is arranged in the medium to be injected;
- an actuator device having an actuator, a plunger and a return element;
- and
- a pulse-transmitting device arranged between the valve arrangement and the actuator device, which separates the valve arrangement from the actuator device in a fluid-tight manner and which transmits a pulse generated by the actuator device to the medium to be injected in that manner to open the valve arrangement and inject medium.
A method for injecting a medium by an injection device, the method comprising:
- separating, using a pulse-transmitting device, the valve arrangement from an actuator device in a fluid-tight manner;
- and
- transmitting a pulse generated by the actuator device via the pulse-transmitting device to the medium and then to the valve arrangement to make an injection of medium;
- wherein the injection device includes a valve arrangement that is arranged in the medium to be injected, the actuator device, and the pulse-transmitting device that is arranged between the valve arrangement and the actuator device.
