Definitions

the invention relates to a valve holder for a lift valve of an internal combustion engine according to the type mentioned in the preamble of claim 1.
the invention is based on the German patent application 20 14 575.
a valve control assembly for internal combustion engines with an overhead Camshaft shown.
the cam of a rotating camshaft is actuated by this arrangement a rocker arm, which in turn on the cylinder head side in a ball joint is stored.
the end of the rocker arm facing away from the ball joint side transmits the lifting movement to a side plate via a pressure plate Lift valve.
the valve stem of the globe valve is opposed by valve cone elements Spring force held by valve springs that press against the spring plate.
the spring plate surrounds the pressure element between the rocker arm and valve stem is arranged radially. Part of the cheeks of the pressure plate are in Closing direction of the globe valve from the hole in the spring plate in which it is arranged is out.
a disadvantage of this arrangement is the high design of the valve plate and the Pressure plate and therefore the large moving mass of the valve train.
the object of the invention is a flatter design of the valve plate and pressure plate Realize to minimize the moving mass of the valve train, tilting the pressure plate during assembly of the valve train parts and during service work is safely prevented.
This object is achieved by the characterizing part of the patent claim 1 solved.
This arrangement shortens the overall length of the valve plate in the closing direction of the lift valve optimally, whereby space is gained and the moving Masses in the valve train are reduced. Furthermore, the printing plate falls out prevented by tilting in the hole. Valve train or engine damage that occurs fallen pressure plates can be attributed to the engine interior reliably prevented.
the use of the pressure plate as a valve clearance compensation element according to claim 3 provides a cost-effective, easy-to-manufacture and robust balancing solution of the valve clearance.
Figure 1 shows a sectional view of a valve holder 1.
a pressure plate 6 At the end of the valve stem 2 there is a pressure plate 6.
she is in a cylindrical bore 9 arranged coaxially with the conical bore 8, whose inner diameter is larger than the largest inner diameter of the conical Bore 8 is held radially.
valve cone elements 3, 3 ' With this engagement results in a positive connection between the valve stem 2 and the valve cone elements 3, 3 'guaranteed.
the valve cone elements 3, 3 ' have a conical outer shape. The large outside diameter is on the side of the valve stem end. The valve cone elements 3, 3 'protrude almost up to the height of the valve stem end, but do not touch the pressure plate 6. So is in the assembled valve holder 1 always an annular gap 7 between the Pressure plate 6 and the valve cone elements 3, 3 'available.
valve stem 2 When assembling the arrangement, valve stem 2 is inserted into conical bore 8 introduced from the side facing away from the pressure plate 6. Then will the valve disk 4 with a special tool against the spring force of the valve spring 5 pressed so that the valve stem 2 at least by its guide length in the spring plate 4 extends beyond the edge of the bore 9.
the two valve cone elements 3, 3 ' inserted into the ring grooves 10, 10' on the valve stem 2. Then the contact pressure of the special tool against the spring force is reduced, so that the valve stem 2 with the two valve cone elements 3, 3 'with their slide the conical outer circumference into the conical bore 8. Due to the The spring force of the valve spring 5 now wedges the valve cone elements 3, 3 'in the conical bore 8.
valve cone elements 3, 3 'and the pressure plate 6 reliably prevents this from tipping.
the number of annular grooves 10 on the valve stem 2, in which the valve cone elements 3, 3 'engage vary. You can also more than two valve cone elements 3, 3 'can be installed. For simpler and better Assembly of the pressure plate 6 can be a slip chamfer on the cylindrical bore 9 are attached.
