==PISTON-OPERATED VARIABLE VALVE DEVICE AND A VARIABLE VALVE SYSTEM HAVING THE SAME - A simplified explanation of the abstract==


This abstract first appeared for US patent application 20240102424 titled 'PISTON-OPERATED VARIABLE VALVE DEVICE AND A VARIABLE VALVE SYSTEM HAVING THE SAME

==Simplified Explanation==

The variable valve device described in the patent application includes a cam with profiles for different exhaust valve opening and closing timings, a rocker arm, and a socket with a piston that moves vertically by oil pressure. When the piston protrudes downward from the socket, the rocker arm and cam come into contact, opening and closing the exhaust valve.

* Cam with profiles for different exhaust valve timings
* Rocker arm for valve operation
* Socket with piston for vertical movement
* Oil pressure for piston movement
* Exhaust valve connected to valve bridge
* Contact between rocker arm and cam for valve operation

== Potential Applications ==
The technology can be applied in automotive engines to improve performance and fuel efficiency by optimizing valve timing.

== Problems Solved ==
This technology solves the problem of inefficient valve timing in traditional engines, leading to better combustion and overall engine performance.

== Benefits ==
- Improved engine performance
- Increased fuel efficiency
- Enhanced combustion efficiency

== Potential Commercial Applications ==
"Variable Valve Device for Automotive Engines" - Optimizing engine performance and fuel efficiency in the automotive industry.

== Possible Prior Art ==
Prior art may include similar variable valve timing devices used in automotive engines for improving performance and efficiency.

== Unanswered Questions ==

=== How does the oil pressure control the movement of the piston in the socket? ===
The patent application does not provide detailed information on how the oil pressure is precisely utilized to control the vertical movement of the piston within the socket.

=== Are there any specific materials or manufacturing processes mentioned for the components of the variable valve device? ===
The patent abstract does not specify the materials or manufacturing processes used for the cam, rocker arm, socket, piston, or other components of the variable valve device.


==Original Abstract Submitted==

a variable valve device includes: a cam having profiles with different exhaust valve opening and closing timings, a rocker arm, and a socket having a piston. in particular, an exhaust valve is connected to a valve bridge and the piston vertically moves by oil pressure supplied to an inside of the socket. when the piston protrudes downward from the socket, the rocker arm and the cam come into contact with each other, and the exhaust valve is opened and closed by the cam profiles.
