摘要:
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.
摘要:
There is described a hydraulic connection assembly with a pressure discharge control, which is positionable between an onboard hydraulic circuit of an engineering vehicle and a removable hydraulic equipment. The hydraulic assembly comprises a one-piece body (1, 51) attachable to the outside of the hydraulic machine near the hydraulic equipment and provided with at least one input hydraulic linkage (4, 5; 52) connectable to a pressure line of the hydraulic circuit of the vehicle, at least one coupling (7, 8; 54) suitable for the connection with a feeding input of a removable equipment and a pressure discharge hydraulic linkage (6; 53) connectable to a draining line, at least one normally closed discharge valve (21, 22; 55) positioned between said linkage (4, 5; 52) to a pressure line and said linkage (6; 53) to a draining line and a pressure discharge control (35; 56) operable so as to cause the opening of said at least one normally closed valve (21, 22; 55) for the connection of the above said pressure line to the draining line for discharging the pressure existing in the hydraulic circuit of the vehicle. The discharge valve (21, 22; 55) is of the sliding piston type (31) and the pressure discharge control (35; 56) is formed by a lever (35) rotatable around a transversal axis (36) between a stable resting position and a working position in which a side (37) of said lever (35) exerts an axial thrust on said sliding piston (31) for the opening control of said valve (21, 22; 55).
