    • PROBLEM TO BE SOLVED: To control a pressure pulsation to operate a compressor at a low noise.
      SOLUTION: An oil separator-a muffler 10 has an inner chamber 18 provided with an oil reservoir area 16, and a wall 24 for constituting a separator area and provided with a collision face 28. The wall is constituted to form a flow channel with a gradually changed cross-section communicated with the oil reservoir area. A mixture inlet 12 provides a passage for making a mixture of an oil and a gaseous refrigerant flow from an outside of the oil separator-a muffler into the separator area. The oil is separated from the mixture when the mixture collides with the collision face, and the oil flows into the oil reservoir area. The channel 30 fluid-communicated with the oil reservoir area serves as a passage for the oil from the oil reservoir area to the outside of the oil separator-a muffler. A noise reduction mechanism is provided when the separated gaseous refrigerant passes through the stream channel 30 from the separation area.

    • 要解决的问题:为了控制低噪音操作压缩机的压力脉动。 解决方案:油分离器 - 消声器10具有设置有储油区域16的内室18和用于构成分隔区域并具有碰撞面28的壁24.该壁被构造成形成流动 与油库地区沟通逐渐变化的通道。 混合物入口12提供用于使油和气态制冷剂的混合物从油分离器的外部流入消声器的通道进入分离器区域。 当混合物与碰撞面碰撞时,油与混合物分离,油流入储油区。 与油储存区域流体连通的通道30用作油从储油区域到油分离器外部的通道 - 消声器。 当分离的气态制冷剂从分离区域通过流动通道30时,提供降噪机构。 版权所有(C)2007,JPO&INPIT

    • PROBLEM TO BE SOLVED: To provide a rear housing for a compressor to reduce noise, vibration and harshness without increasing the total size of the compressor, and without causing the flow loss. SOLUTION: The rear housing (20) has an outer wall (22) and an inner wall (24) comprising a suction chamber (26) to store a low pressure fluid and a discharge chamber (28) to store a high pressure fluid. An inlet (30) and an outlet (34) are fluid-communicated with the suction chamber and the discharge chamber respectively. The outlet has a discharge passage (36) comprising a tubular member (38) projecting into the discharge chamber. A side wall (44) of the tubular member has a plurality of holes (50) to fluid-connect the discharge chamber and a discharge passage. The total sectional area of a plurality of the holes is substantially equal to the cross sectional area of the discharge passage, which brings about an appropriate amount of fluid flow in a state where the loss is minimized.

    • 要解决的问题:提供一种用于压缩机的后壳体,以减少噪音,振动和粗糙度,而不增加压缩机的总尺寸,并且不会导致流动损失。 解决方案:后壳体(20)具有外壁(22)和内壁(24),内壁(24)包括用于存储低压流体的吸入室(26)和用于储存高压的排放室(28) 流体。 入口(30)和出口(34)分别与吸入室和排出室流体连通。 出口具有排出通道(36),其包括突出到排放室中的管状构件(38)。 管状构件的侧壁(44)具有多个孔(50),用于流体连接排放室和排放通道。 多个孔的总截面积基本上等于排出通道的横截面面积,这在损失最小的状态下产生适当量的流体流动。 版权所有(C)2008,JPO&INPIT
