Hydraulic stop valve for a camera crane |
摘要 |
A stop valve for a camera support such as a telescoping camera crane may include a valve pin engagable onto a valve seat, with a pin plate attached to the valve pin. A spring urges the valve pin in a first direction, which may be an opening direction or a closing direction. First and second dampener pins in first and second cylinders are attached to the pin plate. A closed loop fluid filled flow path connects the first and second cylinders. First and second check valves may be used to control flow in the flow path.
