摘要： PURPOSE:To make it possible to prevent a resonance phenomenon without increasing the exhaust resistance, by setting a bypass which connects the upper stream side and the lower stream side of a main flow route in a silencer, with each other, beside this main flow route, and setting plural baffles as resistive bodies, each of which has a through hole, in said bypass. CONSTITUTION:This silencer is formed as connectedly attaching a resonance preventing body 11 which has a main flow route M and a bypass B, to one end of a silencer main body 10, the other end of which is equipped with an exhaust lead pipe 1, and a tail pipe 2 is attached to the end of the resonance preventing body 11. This resonance preventing body 11 is of double-piped structure, formed of an outer pipe 15 and an inner pipe 12, this inner pipe 12 is supported with the outer pipe 15 through plural supporting pieces 19, and the main flow route M is formed between the outer pipe 15 and the inner pipe 12. Then, a bypass B is formed as attaching plural baffles 14 as resistive bodies, each of which has a through hole 13, at the center of it, as an orifice, at the preset intervals, in the inner pipe 12. In this way, the silencing can be performed efficiently, in a simple structure.

摘要： PURPOSE:To reduce exhaust gas resistance so as to improve silencing efficiency by providing a main passage formed in nearly a straight line for exhaust gas not to flow reversely and by-pass passage having resistance inside. CONSTITUTION:To both ends of the body 10 of a silencer are mounted an exhaust pipe 1 and a tail pipe 2 having larger diameter parts 1'' and 2'' respectively on each side of the body 10 of the silencer. The inside of the body 10 of the silencer is divided into plural chambers 5a-5c by plural partition walls 4, and each chamber 5a-5c is connected to each other through intermediate pipes 6 extending through the center of each partition wall 4. And inside each of larger diameter parts 1'' and 2'' and each of intermediate pipes 6 is installed an inner pipe 12, thus a main passage M in which there is no obstruction, is formed. On the other hand, plural resisters 14 having passing ports 13 formed by orifices in the center are mounted inside the inner pipe 12 at specified intervals, thus by-pass passages B are formed.

摘要： PURPOSE:To attenuate the stress exserted to a movable plate and a fixed plate in the thermal elongation of a structure by providing the movable plate in which a movable rod connected to the structure is fitted and a plurality of pin holes in fixed plates laminated alternatively in a fixed box to permit viscous body to flow in the fixed box. CONSTITUTION:A shoe 2 supporting a structure, for example a piping 1 is installed on a frame bed 3, and the piping 1 and the shoe 2 are secured fixedly to each other to move relative to the frame bed 3. A fixed box 6 is secured fixedly to a support bed 3a integral with the frame bed 3 and receives movably one end of a movable rod 5 having the other end fixed to the shoe 2. And a plurality of movable plates 8 and fixed plates 7 are alternatively laminated through spacers 8a and both plates 7, 8 are provided with center holes into which a movable rod 5 is fitted respectively. Further, the fixed plates 7 are formed over the whole surfaces with a plurality of pin holes 12 through which a viscous body 9 filled in the fixed box 6 can pass. Thus, when the piping 1 is thermally extended, the stress in both plates 7, 8 can be attenuated.

摘要： PURPOSE:To reduce the resistance to exhaust-gas flow and to reduce low-frequency noises, by forming a tank at an intermediate portion of an exhaust pipe, and charging a resistor to the sound wave in a branch pipe opened in the exhaust pipe. CONSTITUTION:A silencer 20 has a tank 22 into which exhaust gas is introduced from an exhaust pipe 21 and a branch pipe 24 disposed in the vicinity of the tank 22 to extend from a downstream-side exhaust pipe 23. One end of the branch pipe 24 is opened in the downstream-side exhaust pipe 23 while the other end of the branch pipe 24 is closed. A resistor 25 to the sound wave (for instance, a porous material, many orifices or fiber) is charged uniformly in the branch pipe 24. In the above arrangement, it is preferable that the length of the branch pipe 24 is equal to or longer than 1/4 of the wave length of the exhaust noises to be silenced.

摘要： PURPOSE:To prevent damage to a valve shaft and a bearing by making a resilient body to support the valve body of the drain valve of a hydraulic ram via the valve shaft and vertically reciprocating the valve body by the effect of variation in the pressure inside a water chamber. CONSTITUTION:Inside a valve chamber 2, a valve seat 14 which has a drain port 14a therein is arranged and a valve body displacement regulator 15 and a resilient body are disposed above the valve seat 14. A valve shaft 18 passes through both the drain port 14a of the valve seat 14 and the valve displacement regulator 15 and is supported at the upper end by the resilient body 13. The valve body 12 is moved up and down freely according to variation in the direction and pressure of flowing water to open and close a drain valve. Because no bearing is required as required in the conventional case, the valve shaft and a bearing can not be subjected to any damage.
