    摘要： A fireproof laminate passing Grade 2 incombustibility according to Japanese Industrial Standard (JIS) A-1321 combustion test is disclosed. The laminate comprises a urethane modified polyisocyanurate foam as a core material and an aluminum foil with a thickness of not less than 0.015 mm as a front surface material piled on the foam through self-adhesion of the foam. When the foam is produced by reacting an organic polyisocyanate with polyols as a modifier in the presence of an isocyanate trimerization catalyst, a blowing agent and other additives, a combination of particular low molecular weight diols with particular high molecular weight polyols is used as the polyol in a special weight ratio and a special total amount per 100 parts by weight of the organic polyisocyanate.

    摘要： An inlet port 15 is divided into a plurality of holes 15a, 15b, 15c, 15 by ribs 61a, 61b, 61c. For example, when liquid refrigerant is compressed within a compression chamber, the inlet valve 21 receives excessive load which is about to bend the inlet valve 21 largely toward the suction chamber side. However, the inlet valve 21 is supported by the ribs 61a, 61b, 61c, and therefore the inlet valve 21 is hardly bent, but the inlet port 21 is positively closed.
