Abstract:
The present disclosure relates to an injection valve. The valve may comprise a fluid inlet tube with a recess, a valve body, a valve needle, a spring element, and an elastic body. The valve body may have a central longitudinal axis and a cavity with a fluid outlet portion. The valve needle may be arranged in the recess of the fluid inlet tube and movable in the cavity. The spring element and elastic body may be arranged in the recess and interact with a portion of the valve body on one side and with a spring rest fixed to the valve needle on another side. The elastic body and the spring element are compressed as the valve needle is moved along the longitudinal axis away from its closing position. The elastic body, in the presence of a fluid pressure in the recess, exerts a fluid-pressure-dependent longitudinal force on the valve needle.
