PURPOSE: A swash plate type expander is provided to improve the operation efficiency of the swash plate type expander by effectively distributing working fluids to pistons through a distribution valve. CONSTITUTION: A swash plate type expander comprises a distribution valve(110), a plurality of pistons, a shaft, a first cam(140) and a second cam(150) The distribution valve comprises a first valve(118) and a second valve(119). The plurality of pistons receives working fluids passed through the first valve and moves inside a housing with pressures of the working fluids. A swash plate is rotated inside the housing with being tilted by the pressures from operations of the pistons. The shaft transfers power by being rotated inside the housing according to rotations of the swash plate. The first cam is protruded from the shaft and opens/closes the first valve selectively according to the rotations of the shaft. The second cam protruded from the shaft and rotated with the first cam opens/closes the second valve selectively according to the rotations of the shaft. The second cam guides the working fluids, which are passed through the pistons and collected by the second valve to exhaust lines. |
