Title:
HYDRAULIC CIRCUIT OF RAM CYLINDER
Document Type and Number:
Japanese Patent JP2015004424
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To efficiently perform venting and draining by a hydraulic circuit of a ram cylinder having two feed/discharge circuits.SOLUTION: A ram cylinder 1 is inclined and arranged, one of the two ports 4a, 4b is arranged at an upper-side corner on an apex of an inclined cylinder 3, the other is arranged at a lower-side corner of a bottom of the cylinder 3, one feed/discharge circuit 19a is connected to the port 4a arranged at the upper-side corner, the other feed/discharge circuit 19b is connected to the port 4b arranged at the lower-side corner, the feed/discharge circuit 19a connected to the port 4a is connected to vent means, the feed/discharge circuit 19b connected to the port 4b is connected to drain means, air staying at the upper-side corner of the apex of the cylinder 3 is thereby introduced to the vent means through the feed/discharge circuit 19a connected to the port 4a, and water staying at the lower-side corner of the bottom of the cylinder 3 is introduced to the drain means through the feed/discharge circuit 19b connected to the port 4b.
