Definitions
- Hydraulic unit for an internal combustion engine with hydraulically variable gas exchange valve drive
- the invention relates to a hydraulic unit for an internal combustion engine with hydraulically variable gas exchange valve train.
- the hydraulic unit comprises:
- the vent channel is inside the housing connected via a throttle point with the pressure relief chamber and opens outside the housing.
- DE 10 2013 213 695 A1 discloses a hydraulic unit of a fully variable hydraulic valve control.
- the hydraulic unit is mounted on the cylinder head of an internal combustion engine, and their hydraulic chambers vent - in the direction of gravity - down into the cylinder head.
- the operational venting of the hydraulic system causes the entrained air bubbles carried by the hydraulic fluid from the interior to the environment of the hydraulic housing and thus prevents air from entering and remaining in the pressure chamber in an excessive amount, wherein the required for the hydraulic gas exchange valve actuation rigidity of the hydraulic fluid at an unallowable level would be impaired.
- the vent also promotes the leakage of hydraulic fluid from the hydraulic housing when the engine is turned off.
- the present invention has the object of developing a hydraulic unit of the type mentioned in such a way that the hydraulic leakage from the hydraulic housing is reduced to such an extent that the hydraulic fluid in the pressure chamber even after a long period of inactivity of the internal combustion engine a critical for their startup level not below.
- the venting channel should have a siphon with a respective first channel section leading downwards with respect to the directions of gravity and the venting direction and with a second channel section leading upwards.
- the bottom section of the siphon runs with the gas exchange valve closed below the boundary of the pressure chamber from the slave piston.
- the siphon has two functions: First, it forms with the up leading second channel section, a hydraulic reservoir which is filled at the time the engine is shut down with hydraulic fluid and then the cooling-induced shrinkage of the hydraulic fluid in the hydraulic chambers - depending on the volume of the reservoir - partially or completely compensated.
- the falling level in the second channel section causes a shortening (via the communicating tubes) of the hydraulic or oil column bearing on the slave piston, so that the low pressure in the pressure chamber ideally completely prevents its leakage.
- the dimensioning of the venting channel which determines the volume of the hydraulic reservoir can also be relevant for the state in which the level in the lowermost section of the siphon drops to such an extent that it is not possible to avoid sucking back air via the first channel section. It is only from a minimum size of the channel cross section that air bubbles can rise without displacing the overlying oil column in front of it and displacing it into the pressure relief space. Since the sucked-back air bubbles rise through the oil column standing in the first passage section and virtually reclose, the leakage-inhibiting negative pressure in the hydraulic housing is maintained.
- two slave pistons 8 are guided per cylinder, which drive the gas exchange valves 2 on the outside of the housing and bound the common pressure chamber 5 on the housing side.
- an electromagnetic hydraulic valve 9 in this case a normally open 2-2-way valve interrupts in the closed state, the connection between the pressure relief chamber 6 and the pressure chamber 5.
- a piston accumulator 10 is connected to receive the displaced hydraulic fluid.
- the pressure relief chambers 6 are connected via a hydraulic connection, not shown, on the hydraulic housing 4 to the hydraulic circuit, ie the oil circuit of the internal combustion engine.
