Description
DESCRIPTION
DAMPING PISTON WITH ORIFICE CONTAINING WAVE PROFILE
TECHNICAL FIELD
The invention relates to a damping piston having a wave profile orifice for use in weapon systems and in all types of high shock and force structures.
In particular, the invention relates to a damping piston having an orifice comprising a wave profile which, as the hydraulic fluid passes between the profile and the housing, generates turbulence and increases the losses in the flow, thereby providing greater shock damping over a shorter distance.
KNOWN STATUS OF ART
In damping pistons, the travelling load is stopped smoothly and slowly by a constant resistance force during the entire shock absorber stroke. The load is decelerated with the lowest possible force in the shortest possible time to avoid damaging force peaks and shock damage to machines and equipment.
In the present art and as seen in the patent application numbered US2022065321, it is seen that the orifice structure of the damping pistons consists of straight channels. Here, the fluid is allowed to pass through these orifices and thus damping is realised. However, during this process, the stroke distance of the mechanism is insufficient to damp the movement in high force systems.
As a conclusion, for the solution of the above mentioned problem in the present art, the requirement to a new economical, useful practical damping piston and the inadequacy of the current solutions have made it compulsory to make an improvement in the relevant technical field.
OBJECTIVE OF INVENTION
The present invention relates to a damping piston having an orifice with a wave profile for use in weapon systems and all kinds of high shock and force structures, which has been developed to eliminate the above-mentioned disadvantages and to bring new advantages to the relevant technical field.
The most important objective of the invention is to generate turbulence in the flow in that region with the wave profile and to increase the losses in the flow and to dampen more shock at a shorter distance.
The structural and characteristic specifications and all the advantages of the invention will be more clearly understood by the following figures and the detailed explanation written with reference to these figures, and therefore this evaluation should be carried out by taking these figures and detailed explanation into consideration.

DETAILED STATEMENT OF INVENTION
In this detailed statement, the preferred embodiment of a damper with an orifice containing a wave profile is only explained for a better understanding of the subject and without causing any limiting effect.
Figure 1 shows the damper with an orifice containing the wave profile of the invention and its details. In our invention, turbulence is generated during the flow of the hydraulic fluid (40) in that region with the wave profile (21) used. Thus, by increasing the losses in the flow with the turbulence generated, more shock damping is provided at a shorter distance.
While the force coming to the piston connection point (50) realises the pre-damping with the effect of the spring (10), the hydraulic fluid (40) inside performs high damping by passing through the orifice holes of the profile (20) and the wave profile (21) housing (30). Thanks to the turbulence generated by the wave profile (21) as the hydraulic fluid (40) passes through it, more force damping is achieved at a shorter distance.
With the completion of the force on the system, the piston will be stabilised by changing the direction of the hydraulic fluid (40) as the spring (10) inside pushes the piston back.
The exclusivity scope of this invention is determined in the claims section, and cannot be limited with the expressions provided above for the purpose of illustration by no means, it is obvious that a person skilled in the art can demonstrate the novelty revealed in the invention by using similar embodiments and/or can apply this embodiment in
other areas of similar purpose used in the art. It is therefore obvious that such embodiments will not accommodate the criterion of overcoming novelty and in particular the known status of art.
Claims
1- It is related to the damping piston used in weapon systems and all kinds of high shock and force structures, and is characterised by the fact that it contains a wave profile (21) that provides more shock damping at a shorter distance by increasing the losses in the flow by generating turbulence as the hydraulic fluid (40) passes between the profile (20) and the housing (30).
