The lock pin with a spring built into the rod cover or head cover locks when moved into the groove in the piston rod assembly.
1) Locking action: When the cylinder reaches the stroke end and back pressure is exhausted from the port on the end lock mechanism side, the spring moves the lock pin forward and into the groove in the piston rod, locking the product.
2) The cylinder starts to operate only after the lock pin has been pushed back, thus unlocking the product, because due to the meter-out control of the lock release, the pressure in the end lock mechanism rises faster than the cylinder starts to move. As described above, the locking mechanism is automatically controlled during normal cylinder operation.
Therefore, it is a locking mechanism that can be operated only with a 5-port 2-position valve, similar to a standard cylinder. Note that the cylinder can only be locked at the stroke end.
