In order to solve the problem mentioned above, for example, the hose itself is made of a highly elastic material and the si* pressure caused by the infestation is alleviated by partial expansion of the hose, or the method is to provide an orifice member tube inside the hose. Some methods have been proposed, such as absorbing the energy of K and Ca II and blocking the transmission of dynamic pressure, but none of them are sufficiently effective in reducing noise.

The latter method also has the disadvantage of high energy consumption. In addition, the applicant has determined that the inside of the hose is made of stainless steel or has a cylindrical shape [i111! Insert the t, ff spiral tube or fII&tube and attach it to the pump side connection fitting, and pass the pressure fluid inside the spiral tube, etc., and use it as a buffer space between the jump chamber of the hose and the spiral tube. How to use the dormitory is explained (Reference No. 56-1026034!j). However, Nire et al.'s product can collect the pre-pressure t@ inside the hose, so it can be configured in a very simple manner, and it has the advantage of being cheap. The pulsating pressure at the hose outlet should be 20-40%.
It almost completely absorbs noise from cars, etc.
It was not sufficient for prevention.

The 1ivi wave reflected in the resonance box before is reflected by the opposing 111Mll11 of the resonance box and moves along with the pressure oil flowing out from the act boat (3b) to the pressure hose (.). The pressure oil further passes through the pressure hose () and moves inside the gearbox (KlF), but since the pressure hose is flexible, the partial expansion of the pressure hose (11K) causes a dynamic wave. When it is absorbed and reaches the gear box, it is extremely moldy. #iL of pulsating waves selectively absorbed in the resonance box!
