Definitions
- the invention relates to an internal combustion engine with camshafts and a device for the relative rotation angle adjustment of one of the camshafts to a drive wheel according to the features in the preamble of patent claim 1.
- An internal combustion engine equipped in this way is known, for example, from EP-B-0 245 791 / DE 36 16 234.
- the linear motor proposed here as a hydraulic motor is in hydraulic connection with a pump which is arranged separately from the internal combustion engine.
- a hydraulic pump arranged on the internal combustion engine for supplying a hydraulic motor which serves to adjust the angle of rotation of a camshaft has been proposed in the unpublished EP-A-0 363 600 / DE 38 34 857.
- the hydraulic pump driven by a first camshaft and the hydraulic motor cooperating with a second, adjustable camshaft are each designed in the vane type and are structurally arranged in a housing separate from the internal combustion engine.
- the invention has for its object to develop a generic internal combustion engine such that a particularly efficient hydraulic motor with a small structure - such as. B. the linear motor proposed in DE-A-36 16 234 - can be combined in a structurally simple manner with an efficient pump in a small installation space.
- claims 2 with 6 embodiments of the invention are specified, the respective pump being essentially a finished part to be attached to the housing cover.
- claims 7 and 8 describe an embodiment of the invention in which the pump is essentially formed from parts integrated on the housing cover of the internal combustion engine on the one hand and on the driving camshaft on the other hand.
- An internal combustion engine 1 (not shown in more detail) is equipped with an intake valve-controlling camshaft 2 - in the further intake camshaft 2 - and with an exhaust valve-controlling camshaft 3 - in the further exhaust camshaft 3.
- the inlet camshaft 2 is assigned a device 4 for the relative rotation angle adjustment of the inlet camshaft 2 to a drive wheel 5.
- the device 4 comprises an adjusting arrangement 6 on the camshaft side, the construction of which is essentially described in DE-A-36 16 234.
- An actuation arrangement 7 is assigned to the mechanical adjustment arrangement 6, which is arranged essentially in the front-side recesses of the intake camshaft 2 and is provided in a housing cover 8 which is detachably arranged on the internal combustion engine 1.
- the actuation arrangement 7 comprises a hydraulic motor 9, which is provided as a linear motor formed from a cylinder / piston unit.
- a pump 10 is arranged on the detachable housing cover 8 of the internal combustion engine 1, the pump 10 being arranged on the housing cover 8 in a drive arrangement with the exhaust camshaft 3 of the internal combustion engine 1.
- the pump 10 which is essentially designed as a finished part, is arranged via its outer contour 11 in a recess 12 of the housing cover 8, the pump 10 via a part of its outer contour 11 with a part of the recess 12 in the housing cover 8, a chamber 13 for pump 10 Limited pressure oil.
- the pressure oil chamber 13 is connected to a control chamber 16 of the hydraulic motor 9 via lines 15 integrated in the housing cover 8 and connected to a control device comprising a controllable clock valve 14.
- the pump 10 inserted into the recess 12 of the housing cover 8 is by means of a clamping cover 17 arranged securely.
- the clamping cover 17 and the housing cover 8 each have a bearing 19 for mounting a shaft 21 which carries an eccentric 20 of an eccentric radial piston pump 10, this shaft 21 being connected to the exhaust camshaft 3 via a plug arrangement 22 in a drive-proof connection.
- the shaft 21 of the eccentric radial piston pump 10 carrying the eccentric 20 is connected in one piece to the exhaust camshaft 3 and the shaft 21 is supported only via a bearing 19 arranged in the housing cover 8.
- the internal combustion engine 1 'of FIG. 2 differs from that of FIG. 1 in that a detachably formed housing cover 23 comprises a fixed slide ring 24 eccentrically arranged with respect to the exhaust camshaft 3 of an internally pressurized radial piston pump 25, the rotor 26 of which is guided with the radially movable one Piston 27 is arranged on the exhaust camshaft 3 in a rotationally fixed manner. Furthermore, a pin 28 is fixedly arranged in the housing cover 23 and engages in a bore 29 which is formed centrally in the rotor 26 of the pump 25 in a sliding-sealing manner.
- the pin 28 has blind holes 30, 31 arranged from both ends with channels to the pistons 27 of the pump 25, the suction-side blind hole 30 with a lubricating oil channel 32 arranged in the exhaust camshaft 3 and the pressure-side blind hole 31 with one in the housing cover 23 integrated pressure line 33 is connected.
- a pump 25 which is short in the axial direction and is arranged separately from the hydraulic motor 9 on the housing cover 23 is achieved.
