Title: Hydraulic circuit using counterbalance valve
Inventor: NAKAYAMA AKIRA
IPC: B66C13/20
Filed: 1999-09-21
Abstract: PROBLEM TO BE SOLVED: To prevent generation of the hunting when a motor is driven at low speed and degradation of the responsiveness when the motor is driven at high speed by a simple constitution. SOLUTION: An oil chamber 13a formed on an end part of a spool 12 of a counterbalance valve 10 is communicated with a pipe 15 via a fixed reducer 14, and the oil chamber 13a is communicated with a tank T via a through hole 17 formed in a land part 12a of a spool 12 and a fixed reducer 21. As the spool 12 is moved by the fluctuation in the motor drive pressure P1, the through hole 17 is also moved, and the opening area of a passage to connect the oil chamber 13a to the tank T is also changed. As a result, the ratio Pa/P1 of the pressure Pa in the oil chamber 13a to the motor drive pressure P1 is increased as the movement of the spool 12 is increased, and when the movement of the spool 12 is small, the pressure fluctuation of the oil chamber 13a is reduced to prevent the hunting.  When the movement of the spool 12 is large, the pressure fluctuation of the oil chamber 13a is increased to improve the responsiveness.
