Abstract

PURPOSE:To interrupt the sound of air suction from a resonator by a method in which a resonator is connected to an air suction duct, and a partition chamber having duct-connecting tubes is integrally formed on the outside of the resonator. CONSTITUTION:During the startup of an engine 1, air sucked from the engine room 7 is taken into a collector 3 through an air suction duct 5. The air suction sound to be generated from the air suction duct 5 is damped by a resonator 11, and at the same time air in a partition chamber 15 is evacuated by the air suction pressure of the engine to increase the degree of vacuum. Resonance sound coming from the resonator 11 can be exactly interrupted by the partition chabmer 15 and also the internal arranging space of the engine can be reduced to a minimum because a vacuum tank is integrally formed for automization of an actuator.

っていた。However, the devices described in these publications have a structure in which the intake noise generated from the intake duct is interfered with by a resonance box (resonator) to attenuate the intake noise, but it is not possible to extract it from the resonance box itself to the outside. Since no countermeasures were taken for the resonance sound, there was a problem in that the silencing effect was not more than a certain level. Apart from these problems, due to the automation of acticotter vibration in recent years, the number of cases in which vacuum is used has increased, and the placement of the vacuum tank for this purpose has also changed since 1983. The problem of installation space due to the addition of a new department could not be solved by any means necessary, as shown in Publication No. 56682.

When the cone gin 11 is started, the interior of the compartment 15 becomes negative pressure due to the intake pressure, and is made of a 4M structure which functions as a vacuum tank 23. In addition, in the compartment 15 that serves as the vacuum tank 23, in addition to the connection string 17.19 of the Doug 1, as shown in FIG. Connect each duct connecting pipe 25, 27, 29 to stage 4-J.
Even if the U compartment 15 is structured as a vacuum tank 23 with multiple functions, it is not possible.

高まる。According to the engine intake structure configured in this way, during the startup of the engine 1, intake air from the first engine room 7 is taken into the receiver 3 via the intake duct 1-5. At this time, the intake noise generated from the intake ducts 1 to 5 is attenuated by the resonator 11. At the same time, the air in the J stiffness compartment 15 is removed by the engine's intake pressure, increasing the degree of vacuum.
