Title:
作業車に内蔵された油圧系と移動可能な油圧装置との間に設置可能な圧力開放制御手段付きの油圧接続装置
Document Type and Number:
Japanese Patent JP5101614
Kind Code:
B2
Abstract:
A hydraulic assembly comprises a one-piece body attachable to the outside of the hydraulic machine near the hydraulic equipment and provided with at least one input hydraulic linkage connectable to a pressure line of the hydraulic circuit of the vehicle, at least one coupling suitable for the connection with a feeding input of a removable equipment and a pressure discharge hydraulic linkage connectable to a draining line, at least one normally closed discharge valve positioned between the linkage to a pressure line and the linkage to a draining line and a pressure discharge control operable so as to cause the opening of the at least one normally closed valve for the connection the pressure line to the draining line for discharging the pressure existing in the hydraulic circuit of the vehicle. The discharge valve is of the sliding piston type and the pressure discharge control is formed by a lever rotatable around a transversal axis between a stable resting position and a working position in which a side of the lever exerts an axial thrust on the sliding piston for the opening control of the valve.
