Problems solved by technology

However, today's solutions often encounter certain limitations, such as composite valve seats, large size or limited amplification
In addition, it is difficult to make serial connections with this technique
[0006] The lever principle is simple and easy to connect in series, but some technical design problems make it difficult to find an integrated solution to make it frictionless and powerful, low loss, low mass, high resonance frequency, large amplification factor, small size and low manufacturing cost

Embodiment Construction

[0038] The present invention will be further described in detail below through specific embodiments in conjunction with the accompanying drawings.

[0039] An example of a device prepared according to one embodiment of the invention is based on figure 1, represented by the first crossbar 10 . The crossbars 10 and 12 are angled and connected vertically to the base plate 19 in line with the lever. The force F0 keeps the crossbar pressed against the base plate 19 . Via the foil 13 (orthogonal relation to the crossbar), the crossbar is placed in a downward movement d. In this way, the length X1+X2 of the crossbar constitutes a lever with a magnification factor of (X1+X2) / X1.

[0040] The movement 6 of the crossbar 10 is transmitted directly to the crossbar 11 as an upcoming movement. Once reached, the crossbar 11 is pivoted longitudinally about the support element 14 . Due to the angle between the levers, the rotational movement is preferentially absorbed by the first crossba...

Abstract

The invention relates to a mechanical amplifier which converts a small motion vibration amplitude to a big motion vibration amplitude. The method includes two or more transverse levers which are serially connected at an angle. An unexpected motion generated in the structure is absorbed by the structure through a torsioning function. Each transverse lever is a mechanical amplifier. A total amplification function is a product of the combination amplification function of the transverse levers which are serially connected. The invention relates to a device including two or more connected transverse levers, wherein the connection angle of the transverse levers is preferably 90 DEG.

Description

technical field [0001] The invention belongs to a mechanical amplifier. Furthermore, the invention relates to a mechanical amplifier for amplifying the motion produced by an actuator device, such as a piezoelectric actuator. Background technique [0002] As technology continues to advance, the demand for mechanical amplifiers has increased, mainly in the field of piezoelectric ceramics. Piezoelectric ceramics are being increasingly used in actuator devices instead of electromagnetic solutions. The reason is that the F / M ratio is almost 10 times larger with piezoelectric ceramic technology compared to electromagnetic technology. An example where electromagnetics are replaced by piezoelectric actuators is fuel injection valves in the automotive industry. It leads the generation of a new generation of low-fuel consumption engines. This piezoelectric actuator technology has made it possible to control fuel injection in milliseconds per piston movement.
