A fluid machinery includes: a crankshaft, a cylinder sleeve, a crossed groove structure and sliding blocks, and there is a first included angle A between two eccentric parts of the crankshaft. The crankshaft and the cylinder sleeve are eccentrically arranged and have a fixed eccentric distance therebetween. The crossed groove structure has two limiting channels sequentially arranged along an axial direction of the crankshaft, and there is a second included angle B between the extension directions of the two limiting channels. The first included angle A is twice of the second included angle B. The two eccentric parts are correspondingly extended into two through holes of the two sliding blocks, and the two sliding blocks are correspondingly arranged in the two limiting channels in a sliding manner, to form a volume-variable cavity.
