Japanese Patent JP2001523803
Kind Code:
A
Abstract:
The purpose of the invention is to provide a valve actuator with an activating pin of a simple construction. This task is solved by the present invention as recited in claim 1; where in the first position the piston (77, 84) is at a first predetermined distance from the first end (92) of the cylinder (70, 99, 136, 142), in the second position the piston (77, 84) is at a second predetermined distance from the first end (92) of the cylinder (70, 99, 136, 142), said second predetermined distance being larger than said first predetermined distance, and the housing (100, 104, 120, 121, 149, 132) comprises a channel (71, 72, 73, 74, 80, 81, 133, 134, 135) for allowing the conduction of gaseous and/or liquid media between the cylinder (70, 99, 136, 142) and the coupling section (103, 110, 130, 147) when the piston is in the first piston position, inhibiting the conduction of gaseous and/or liquid media between the cylinder (70, 99, 136, 142) and the coupling section (103, 110, 130, 147) when the piston is in the second piston position.
