摘要： A continuously variable hydraulic transmission operatively interconnects a transmission mechanism and a clutch mechanism. The hydraulic transmission includes an oil pump having an inlet port and an outlet port and a transmission ratio control member such as a swash plate which is displaceable for varying the transmission ratio between a higher-speed position, a lower-speed position, and a neutral position, an oil motor having an inlet port and an outlet port and drivable by the oil pump, a first oil passage hydraulically interconnecting the outlet port of the oil pump and the inlet port of the oil motor, a second oil passage hydraulically interconnecting the inlet port of the oil pump and the outlet port of the oil motor, a housing accommodating the oil pump, the oil motor, the first oil passage, and the second oil passage, and an oil passage control unit for selectively bringing the first oil passage into and out of hydraulic communication with the second oil passage. The oil passage control unit is fully accommodated in the housing and actuatable by the transmission ratio control member to bring the first and second oil passages into hydraulic communication with each other only when the transmission ratio control member is near the neutral position.

摘要： An air intake noise reduction apparatus is provided which can effectively reduce air intake noise even with simple construction requiring a small number of components. Four air intake passages 24, 25, 26, 27 which each have different passage lengths are formed by connecting an upper wall 17 and a lower wall 18 of an air intake noise reduction duct 11 which are flattened in a vertical direction with three partition walls 21, 22, 23. Air intake noise can be reduced by making pulsating air interfere with one another which is generated in the plurality of air intake passages 24, 25, 26, 27 which each have the different passage lengths in such a manner as to have different phases shifted from one another. In addition, since the partition walls function as a reinforcement rib, the rigidity of the air intake noise reduction duct 11 can be enhanced. Moreover, since the partition walls are formed in such a manner as to extend along an intake air flow direction, increase in intake air resistance can be suppressed to a minimum level.

摘要： A motor vehicle intake muffler duct is formed by integrally bonding an upper duct, a lower duct and a separator interposed between them. Three airways are formed between the upper duct and the separator, seven muffler chambers are formed between the lower duct and the separator, and the airways and the muffler chambers are communicated with each other through vent holes which are formed in the separator. An intake muffler duct in which multiple muffler chambers are integrated with the airways, can be formed from only three components, which are an upper duct, a lower duct and a separator, and moreover although it has a compact structure, it is possible to reduce the intake noise effectively.
