A valve apparatus for an excavator breaker is provided to directly embed a control valve in a cylinder to adjust the lifting of a piston, so that the erroneous operation of a valve is prevented. A valve apparatus includes a valve chamber(13), a valve sleeve(50), a control valve(40), and a valve plug(60). The valve chamber is provided at one side of a cylinder(10) having a piston(20). The valve sleeve communicates with upper and lower fluid spaces of the cylinder. The control valve is inserted into the valve sleeve. The valve plug covers an upper portion of the control valve. The valve plug is inserted into the valve chamber of the cylinder. Upper and lower fluid grooves are formed on upper and lower sectional areas. |
