#CMT# #/CMT# The valve (25) has a valve body (27), from which a valve piece (41) is extended out. A closing body (30) is back and forth movably guided on the valve piece to reduce or increase pressure in a control chamber. A spring stop element (44) for a control valve spring (31) is fixed at a free end (45) of the valve piece. The control valve spring is fixed between the spring stop element and the closing body. The valve piece is extended outside at distance over the closing body, which is larger than circumference of the control valve spring in an inserted condition. #CMT#USE : #/CMT# Control valve for a fuel-injection valve device (claimed), which is utilized for injecting fuel into a combustion chamber of an internal combustion engine over an injection opening. #CMT#ADVANTAGE : #/CMT# The spring stop element for the control valve spring is fixed at the free end of the valve piece, such that the fuel-injection valve device is manufactured in a cost-effective manner, and assembling of the control valve spring is performed in a simple and cost-effective manner. #CMT#DESCRIPTION OF DRAWINGS : #/CMT# The drawing shows a longitudinal sectional view of a control valve. 25 : Control valve 27 : Valve body 30 : Closing body 31 : Control valve spring 41 : Valve piece 44 : Spring stop element 45 : Free end. |
