Abstract: This invention aims at obtaining an oil feed mechanism-carrying rotary compressor capable of increasing a feed rate of an oil to a sliding portion, improving a lubricating effect and a cooling effect, and discharging abrasion powder and dust from an oil feed system. To achieve this object, the present invention is formed by providing a bottomed cylindrical oil bore (213) in the central portion of a shaft (206), and a spiral oil groove (224) in an outer circumferential surface thereof, allowing communication between one end portion of the oil bore (213) and one end portion of oil groove (224), i.e. between a bottom portion (213') and an end portion (224') via an outlet port (214), and providing a suction passage (221A) for allowing communication between the other end of the oil bore (213) and an oil (2), and a discharge passage (223B) for communication between the other end (224') and the oil (2).

Abstract: A flow diverter provided with a flow inlet part (22) having a throttle formed at one end, a roughly cylindrical flow diverting part (24) having a flow-striking wall (23) for changing the direction of the flow coming from the inlet part (22), and a plurality of outlet pipes (25) connected to the peripheral wall of the flow diverting part (24) while arranged in the radial direction, wherein gaseous phase of the refrigerant flowing into the inlet part (22) is evenly mixed with liquid phase thereof to be diverted uniformly in quantity. Because of the arrangement of the outlet pipes (25) connected to the peripheral wall of the roughly cylindrical flow diverting part (24) in the radial pattern, the flow diverter can be reduced in size and manufacturing cost.

Abstract: A foamed heat-insulating material for cold storage and refrigerator, wherein the amount of a fluorocarbon blowing agent is reduced, which is prepared by stirring a mixture of a carbon dioxide adsorbent having a hydrophobic surface with a water-containing premix component and an isocyanate component. The amount of a fluorocarbon blowing agent can be reduced by using water as the blowing agent. Carbon dioxide generated by the reaction of water with the isocyanate is removed by adsorption with the carbon dioxide adsorbent after the foaming to thereby obtain purified fluorocarbon gas from gases enclosed in the cells.
