Abstract
An inlet valve charges an inner chamber with liquid and has a first axis and an inlet opening with a tool that automatically recloses. The inlet valve has a valve body with a blocking element, and a pressing part; a valve space enclosing the valve body at least partly; a spring mechanism and a sealing element. An open passage region opens into the liquid passage of the pressing part and into the valve space. The spring mechanism presses a sealing surface of the blocking element against the sealing element in a closed position of the valve body. The valve body of the inlet valve can be brought to an open position by pressing the pressing part against the resistance of the spring mechanism. Chamber systems and sample containers with such inlet valves are also disclosed.
