Title: Friction material
Inventor: YAMAZAKI KENICHI
IPC: F16D69/00
Filed: 1995-10-19
Abstract: PROBLEM TO BE SOLVED: To prevent crack initiation at the interface between an intermediate layer incl. pad layer and a heat insulation layer and facilitate manufacture by enclosing the intermediate layer with pad layer so that the surface of the intermediate layer including heat insulating material layer joined with one surface of a metal plate is not exposed. SOLUTION: A pad layer 18 and heat insulating material layer 20 constitute a lining 16, and a heat insulating material layer 20 joined with one surface of a metal plate 14 is enclosed with the pad layer 18. Therefore, the interface between two layers can be covered with the pad layer 18. Therefore, the part around the surface of the pad layer 18 is rapidly cooled when the lining 16 consisting of the heat insulating material layer 20 and pad layer 18 is heated followed by heat radiation, but the part around the interface between the layer 20 and pad layer 18 is cooled more slowly than the part around the surface of the pad layer 18. Accordingly it is possible to cool the lining 16 with no risk of steep widening of the difference in the contraction ratio (linear coefficient of thermal expansion) between the two layers, and crack initiation in the interface can be precluded.

Filed: 1989-10-20
Abstract: PURPOSE:To prevent cooling gas and oil from flowing in the same passage and oil from rising due to cooling gas by installing a guide plate on the upper inner wall of a sealed container so that a discharge port side may be made protruded between the discharge port and plural passages, and the plural passages may be located inside a curve. CONSTITUTION:Mixture gas consisting of discharged cooling gas and oil collides with the upper inner wall of a sealed container 1 and separates in oil and cooling gas, and oil flows into the upper outer periphery 5b of a fixed scroll 5 along the upper inner wall of the container 1. At this time, oil flows along the upper inner wall of the container 1, and its flow direction is changed by a guide plate 19. Therefore, oil does not flow into a cooling passage 18 directly but into the upper outer periphery 5b of the scroll 5. Then the oil which stays on the upper outer periphery part 5b of the scroll 5 passes through passages 18a, 18c on both sides of the passage 18, and flow into a space between a frame 7 and a motor 3. Thus, oil flows in the passages 18a, 18c, so that cooling gas passes mainly through a passage 18b. Namely, coolant flows mainly into a central passage 18b out of there cooling passages, and oil flows mainly in the outside passages 18a, 18c.
