Abstract
A separating wall having a valve opening is disposed between a chamber holding a high pressure and a chamber holding a low pressure. The valve seat is closed by a ball acting as a valve body. For a quick opening of the valve, an actuating member imparts a lateral impact to the ball, thereby lifting the ball off the valve seat. Setting the ball back onto the valve seat is effected under the influence of the gas flow passing through the valve opening. The valve has extremely short switching times and allows for a high repetition frequency.
