Description

TARIFNAME BIR PISTON Mevcut bulus, pnömatik/hidrolik itki pistonlari ile ilgilidir. DESCRIPTION ONE PISTON The present invention relates to pneumatic/hydraulic thrusters.

Bilinen teknikte, dogrusal hareket saglamak için çesitli hareket elemanlari veya hareket sistemleri yer almaktadir. Bu baglamda dogrusal hareketin saglanmasi için dogrusal motorlar ve selenoidler kullanilmaktadir. Ancak dogrusal motorlarin ve selenoidlerin güç tüketimi, özellikle uygulanacak kuvvet miktarinin yüksek oldugu durumlarda yüksek olmaktadir. Ayrica, dogrusal motorlarin ve selenoidlerin tepki süresi de nispeten yüksektir. In the prior art, various motion elements or motion elements are used to provide linear motion. systems are included. In this context, linear motion is required to provide linear motion. motors and solenoids are used. However, the power of linear motors and solenoids consumption is high, especially when the amount of force to be applied is high. is happening. In addition, the response time of linear motors and solenoids is relatively high.

Dogrusal hareket saglanmasi için bilinen teknikte kullanilan uygulamalardan bir tanesi de pnömatik pistonlardir. Pnömatik pistonlar, içerisinde bir yuva bulunan bir gövdeyi, bahsedilen gövde içerisinde hareket edebilen bir hareketli elemani ve gövde içerisine bir akiskan gönderilmesi ile bahsedilen hareketli elemanin hareket ettirilmesini saglayan bir akiskan girisini içermektedir. Bahsedilen akiskan girisinden gövde içerisine hava gibi bir akiskan basilmasi sayesinde gövde içerisinde bir basinç olusturulmakta ve olusturulan basincin etkisiyle hareketli elemanin hareket etmesi saglanmaktadir. Ancak geleneksel uygulamalarda, gövdenin iç hacminin nispeten fazla olmasi sebebiyle hareketli elemanin hareket etmesi için gereken akiskan miktari da fazla olmaktadir. Bu durum da, hareketin yavas olmasina (bir diger deyisle tepki süresinin yüksek olmasina) sebep olmaktadir. One of the applications used in the known technique to provide linear motion is are pneumatic pistons. Pneumatic pistons consist of a body with a slot inside, a movable element movable within said body and a a device that enables the said moving element to be moved by sending fluid. contains the fluid input. From the aforementioned fluid inlet, an air, such as air, into the body A pressure is created in the body thanks to the fluid pressure and the created With the effect of pressure, the moving element is provided to move. However, traditional In applications, due to the relatively large internal volume of the body, the movable element The amount of fluid required to move is also high. In this situation, the movement causes it to be slow (in other words, high reaction time).
