STRUCTURE, FUNCTION AND MAINTENANCE STANDARD PISTON VALVE
PISTON VALVE
For blade lift cylinder
Outline
• The piston valve is installed to the piston of the blade lift cylinder. When the piston moves to the stroke end, the piston valve relieves the oil sent from the work equipment pump to lower the oil pressure applied to the piston.
The piston valve also relieves the oil before the piston reaches the bottom or head of the cylinder to reduce the impact made at the stroke end and lower the surge pressure generated by the impact.
Operation
1. When piston valve is "closed"
The oil from the work equipment pump acts on piston (2) and piston valve (3). Then, piston valve (3) is pushed to the right to seal the tapered part of piston valve seat (4). As a result, the oil pressure in the cylinder rises to move piston (2) to the right.
2. When piston valve is "open"
The end of valve (6) touches the cylinder bottom before piston rod (1) reaches the stroke end, and then valve (6) and piston valve (3) do not move any more and only piston (2) continues moving.
At this time, the oil on the cylinder head side which has been stopped by piston valve (3) is relieved through piston valve seats (4) and (5), thus the oil pressure in the cylinder does not rise any more.
