Hydraulic Drive for Accelerating and Braking Components That Are To Be Moved Dynamically - A simplified explanation of the abstract
This abstract first appeared for US patent application 20240035400 titled 'Hydraulic Drive for Accelerating and Braking Components That Are To Be Moved Dynamically
Simplified Explanation
The abstract describes a proposed configuration for a hydraulic drive system used for accelerating and braking in internal combustion engines or other reciprocating engines. The configuration includes a drive piston with a control edge that prevents the inflow of drive pressure into the drive chamber or the outflow of pressure medium from the brake chamber when a defined travel has been attained. This causes the hydraulic drive force to vanish, become small, or change its sign when the specified travel is reached.
- The drive piston in the hydraulic system has a control edge that corresponds to an inflow opening.
- When a defined travel is reached, the control edge prevents the inflow of drive pressure into the drive chamber.
- The control edge also prevents the low-loss outflow of pressure medium from the brake chamber to the basic pressure level.
- This configuration ensures that the remaining hydraulic drive force becomes small or changes its sign when the specified travel is attained.
Potential Applications:
- This configuration can be applied to gas exchange valves in internal combustion engines or other reciprocating engines.
- It can be used in hydraulic drive systems for accelerating and braking in vehicles or machinery.
Problems Solved:
- Provides a more reliable configuration for hydraulic drives by preventing deviations in the maximum travel of the moving mass.
- Ensures that the hydraulic drive force becomes small or changes its sign when the specified travel is reached, improving control and stability.
Benefits:
- Increases the reliability of hydraulic drives by preventing unexpected deviations in the maximum travel of the moving mass.
- Improves control and stability of hydraulic drive systems by ensuring that the hydraulic drive force becomes small or changes its sign when the specified travel is attained.
Original Abstract Submitted
in order to provide a more reliable configuration for a hydraulic drive for accelerating and braking in particular a gas exchange valve () of internal combustion engines or other reciprocating engines, in particular if the occurring maximum travel of the moving mass can deviate considerably from an expected setpoint position, it is proposed that the drive piston () has at least one control edge () corresponding to an inflow opening (), which, when a defined travel hhas been attained, prevents the inflow of drive pressure pinto the drive chamber () and/or prevents the low-loss outflow of pressure medium from the brake chamber () to the basic pressure level (), wherein the remaining hydraulic drive force vanishes, becomes small or changes its sign when said travel his attained.
