Definitions
- the invention is particularly applicable to use
- Suitable for reciprocating engines the working gas inlet and outlet control slots, or channels are arranged in the region of the upper Kolbentotissue. It is known ⁇ DE-A-1906542), the gas exchange in internal combustion engines by
- the known cylinder seal for laterally moving pistons by means of seals against the gas pressure piston rings can not be made for reasons of space for the sliding sleeve. Rather, here either an embodiment similar to that of a valve in question, i. the sliding sleeve has a conical sealing seat on its edge which controls the channel opening, or it closes off the channel openings, as is known with slider controls
- valve seat-like sealing end face of a sliding sleeve with the same internal diameter throughout differs in the function of conventional valves in that the gas pressure can exert no closing force on the sealing surface. On the contrary, if the
- pressurized gas can get into the resulting gap and seeks to increase it, as a result of which the sliding sleeve can be pressed on or at least continues to leak.
- the object of the invention is therefore the,
- Inner diameter of the sliding sleeve reaches in the region of the sealing end face, i. the outer sealing
- Cylinder located sealing seat are made interchangeable. This can, similar to conventional
- Valve seats a well-suited material to be used.
- Range is swept by the piston and piston rings, suitably a conventional
- the sliding sleeve can be made of high-strength and heat-resistant material in the region of its sealing surface.
- the various materials can be friction welded,
- connection method be connected.
- the advantage of this design with different materials is a higher strength and temperature resistance.
- Fig. 1 shows a cross section through an opposed piston engine. Two pistons 1 and 2 move in opposite directions in one
- Motor housing consisting of two crankcases 3 and 4 and two cylinder halves 5 and 6 which are interconnected by a cylinder center part 7.
- the pistons are driven by two crankshafts 8 and 9, as well as the connecting rods 10 and 11. Their movement is synchronized by a gear wheel 12.
- the pistons run in the sliding bushes 13 and 14, which in turn are slidably guided in the cylinder halves 5 and 6. By their displacement, the
- annular gas channels 15 and 16 are opened and closed independently.
- Fig. 2 shows the details of the aforementioned cross section in the region of the seal of the sliding sleeves 13 and first The sliding sleeve 13 is in the open state and the
- Sealing seat for the sliding bushes is mounted in the cylinder center part 7 and as a conical sealing seat 15 and 16th
- Sliding sleeve is used and their bursting prevented by high gas pressures.
- Condition for a proper function is that the outer diameter of the sealing seat is not greater than the inner diameter of the sliding sleeve and the space behind the. Sealing seat is sufficiently vented, so that there is no pressure builds up in leaky seat there. This purpose of venting serve local grooves 20 which are mounted at some points of the circumference of the fit 19.
- Fig. 3 shows an example of a replaceable seat ring 21, which is held by the flanges 22 and 23, which are fastened by means of the screws 24.
- This embodiment has the advantage that for the seat ring 21, an optimally suitable material can be selected, regardless of the material of the cylinder center part 7. It is also shown that the
- Sealing surfaces having front side of the sliding sleeve can be designed as a separate material-optimized part 25, which is firmly connected to the sliding sleeve.
