摘要： A swash-plate type rotary compressor includes a plurality of cylinders disposed in circumferentially equi-distantly spaced relation to each other around a drive shaft having mounted thereon a swash plate for rotation therewith. The swash plate is rotated to cause pistons to be slidingly reciprocated in the respective cylinders to draw gas containing lubricant and to compress same. Guide walls are provided on both sides of a swash plate chamber for guiding gas introduced into the swash plate chamber to flow over entire side surfaces of the swash plate from an outer periphery toward a center thereof. A plurality of gas guiding passageways are each located between each pair of adjacent cylinders, for guiding the gas flowing to a central portion of the swash plate into at least one low pressure space.

摘要： A compressor of a type in which a plurality of pistons reciprocate in cylinders, the improved compressor in which a mechanism is provided to reduce pulsating of suction pressure in the cylinder head. The inside of the cylinder head is partitioned into a high pressure chamber on the side of the center and a low pressure chamber on the side of the periphery by means of bulkhead formed on the cylinder head. The low pressure chamber communicates the suction holes and the discharge opening formed on the cylinder head. The outer peripheral wall of the low pressure chamber is arranged to reduce a resistance of gas passing through the low pressure chamber as the convex portion constituting the periphery of the connecting bolt and the concave portion constituting the peripheries of the suction holes are connected by means of a connecting portion having a smooth curved surface.

摘要： A compressor of a type in which a plurality of pistons reciprocate in cylinders. A mechanism is provided to reduce pulsating of discharge pressure in the cylinder head. A high pressure chamber formed in the cylinder head is partitioned by a partition plate into a first high pressure chamber communicating with a plurality of discharge holes in the valve plate by means of a discharge valve and a second high pressure chamber communicated with a discharge opening formed in the cylinder head, and the pulsating is reduced by the passing of the gas through the first high pressure chamber and the second high pressure chamber.
