Definitions
- the invention relates to a valve for controlling an injection valve of an internal combustion engine according to the preamble of patent claim 1.
- Such a valve has become known for example from DE 101 46 743 A1.
- a high-pressure side annular space is formed, which is sealed by two axially spaced sealing points, namely a flat gasket and a sealing ring. Due to dynamic processes within the high-pressure side annulus, however, there is a risk that the sealing ring lifts off its intended sealing seat and closes a hydraulic inlet bore in the valve piece of the injector. This can become one
- valve according to the invention with the features of claim 1 has the advantage that a "high migration" of the sealing ring and thus a serious loss of function can be reliably prevented. It has additionally been demonstrated by endurance tests that the introduction of the additional spacer sleeve has no influence on the injector map, i. is map neutral.
- FIG. 1 shows a longitudinal section through the valve according to the invention.
- FIG. 2 the spacer sleeve of Fig. 1 in a perspective view.
- the valve 1 shown in FIG. 1 is used to control an injection valve (injector) of an internal combustion engine and has an annular space 2, which is connected via a fuel line 3 to a high-pressure fuel storage (CommonRail), not shown.
- injector injector
- annular space 2 which is connected via a fuel line 3 to a high-pressure fuel storage (CommonRail), not shown.
- CommonRail high-pressure fuel storage
- the high-pressure side annular space 2 is formed in a stepped bore 4 of the valve housing 5 by a sleeve-shaped guide projection 6 of a valve piece 7 which rests sealingly with a flange 8 on a shoulder 9 of the bore 4 and - axially spaced - on the guide projection 6 by a high pressure Sealing ring (including underlying steel support ring) 10 opposite the valve housing 5 is sealed.
- a valve clamping screw (not shown), the flange 8 is pressed against the shoulder 9.
- a spacer sleeve 11 (valve chamber sleeve) is arranged, which has a plurality of wall openings 12 (FIG. 2).
- the spacer sleeve 11 is pushed onto the guide projection 6 of the valve member 7 and thus forms after installation in the injector a stop for the underlying sealing ring 10, which is thus held at minimum axial distance to the shoulder 9 of the bore 4, so is prevented from "high migration".
- the spacer sleeve 11 is designed so that a rotation on the valve piece 7 can not lead to any functional influence.
- the area ratios of sealing ring 10 and support on the spacer sleeve 11 are chosen so that the forces acting at high pressure can not lead to "flowing around" of the sealing ring 10.
- the filigree contours and wall openings 12 of the spacer sleeve 11 are introduced by means of laser cutting or punching in a metal sheet (board), which is then rolled to form a slot 13 to the spacer sleeve 11.
- the contours and wall openings 12 are chosen so that the function of the valve piece 7 and thus the function of the injection valve is not affected.
- valve piston 14 of the injector is slidably guided in a guide bore 15 of the valve member 7 and limited in the valve piece 7 a control chamber 16.
- the control chamber 16 is connected via an inlet throttle 17 with the annular space 2 and opens via a Outflow throttle 18 in a valve seat opening of a conical valve seat 19, which is provided on the side facing away from the guide projection 6 end face of the valve member 7 for cooperation with a valve closure member 20.
- Control chamber 16 is acted upon by high pressure and thereby displaced the valve or actuator 14 of the injection valve in its lower position.
- the valve closure member 20 In the open valve position shown, the valve closure member 20 is lifted from the valve seat 19 and the valve seat opening released, whereby the control chamber 16 is depressurized and the valve or actuator 14 is moved to its upper position.
