Claim Text:
1. A valve arrangement, comprising: a valve body comprising a fluidic channel having an outlet port; and a valve piston, the valve piston comprising a through opening connecting an end with a piercing end that provides fluid communication between the piercing end and the outlet port to allow fluid to pass through the valve piston, and the valve piston comprising an outer lateral surface having a circular recess formed therein, wherein the valve piston is moveable within the valve body between a first longitudinal position and a second longitudinal position, wherein the circular recess of the valve piston is not in fluid communication with the outlet port, to disable a fluid flow between the outlet port and the end via the circular recess, when the valve piston is in the first longitudinal position within the valve body, and wherein the circular recess of the valve piston is in fluid communication with the outlet port, to enable the fluid flow between the outlet port and the end, when the valve piston is in the second longitudinal position within the valve body.
