Patent ID: 8104739

Claim:
A pulse valve ( 10 ) with a closing body ( 18 ) that cooperates with a valve seat ( 22 ) by at least a valve spring ( 24 ) and, in a first switching position, establishes a flow connection between a supply channel ( 12 ) and a discharge channel ( 14 ) and, in a second switching position, blocks the flow connection, the closing body ( 18 ) periodically moving in a reciprocating motion ( 82 ) between the two switching positions during an actuation of the pulse valve ( 10 ), wherein a hydraulic damping to a movement of the closing body ( 18 ) by a throttle gap ( 70 ) occurs in a damped range ( 62 ), wherein the closing body ( 18 ) is connected via a rod ( 56 ) with a damping disk ( 54 ) made of structural material, the damping disk ( 54 ) provided in a damping cylinder ( 50 ) that is open on a first end face and, except for a guide opening ( 58 ), in which the rod ( 56 ) is guided, closed on a second end face being located opposite to the first end face, and wherein the damping disk ( 54 ) exits the damping cylinder ( 50 ) shortly before the closing body reaches the second switching position.
