摘要： PURPOSE:To enhance the durability by preventing generation of operating sound from a rubber stopper, and by preventing a diaphragm from wrinkling during application of vacuum. CONSTITUTION:A rubber stopper 49 is provided thereon with protrusions 49a and has a matte finished surface. Accordingly, this rubber stopper 49 is not made in close contact with the inner upper surface 41a of the a body 41 even though it is pressed against thereto upon application of vacuum. Accordingly, it is possible to prevent generation of operating sound which would be generated if it were separated from its close contact condition upon change-over into an atmospherically opening condition. Further, no wrinkling occurs in a diaphragm 42 since the wall part 44a of a receiving plate 44 is extended, thereby it is possible to enhance the durability.

摘要： PURPOSE:To enlarge an valve closing range (silent mode) in which a selector valve for changing over exhaust passages in a dural mode muffler is fully opened, in a low speed range of an engine. CONSTITUTION:A vacuum chamber 23 in a vacuum actuator 20 for driving a selector valve 17 is communicated selectively with a vacuum passage 23 communicated with an intake manifold or a passage 34 opened to the atmosphere, through the intermediary of a control valve 32. A vacuum tank 36 is located between the control valve and the intake manifold. A check-valve 37 is connected in the vacuum passage 33 between the vacuum tank 36 and the intake manifold, thereby it is possible to always maintain a high vacuum in the vacuum tank 36.

摘要： PURPOSE:To protect a dural mode muffler from external affection, by providing a mechanism for opening and closing a shut-off valve in a space defined by a muffler body provided in an exhaust pipe, a bypass pipe connected at both ends to the muffler body, the shut-off valve for opening and closing the bypass pipe and the bypass passage. CONSTITUTION:In a dual mode muffler in which a bypass pipe 2 branches once from a muffler body 1 provided in an exhaust passage from an engine, and is then connected to the same. A shut-off valve 3 is provided in the bypass pipe 2. This shut-off valve 3 is provided thereto with an opening and closing mechanism for changing the opening and closing conditions of the valve 3. The mechanism 4 is located in a space defined between the bypass pipe 2 and the muffler body 1. That is, the movable part of the mechanism 4 consisting of a cable, a lever, a spring and the like for operating the shut-off valve is located at a position where it is protected by the bypass pipe 2 and the muffler body 1, and accordingly, it is possible to prevent popping stone splashed mud or the like from impinging upon and sticking to the mechanism 4 so as to hinder the operation thereof. Thus, it is possible to provide a structure which can be hardly subjected to external affection, thereby it is possible to enhance the reliability and durability.
