Valve cylinder interface, assembling method for valve cylinder interface and power generating apparatus of renewable energy type

摘要

A valve cylinder interface is for communication between a working chamber (24) formed by a cylinder part (22) and a piston (26) and a high pressure valve (28) for controlling flow of high-pressure working fluid and a low pressure valve (30) for controlling flow of low-pressure working fluid. The valve cylinder interface is provided with a valve block (38) having a cylindrical intermediate chamber (220) configured to communicate with the working chamber (24), a main port (102) for coaxially connecting the intermediate chamber (220) and the cylinder part (22) to each other, and a communication path (222) for allowing communication between one of the high pressure valve (28) or the low pressure valve (30) and the intermediate chamber (220). The other one of the high pressure valve (28) or the low pressure valve (30) is arranged adjacent to and coaxially with respect to the intermediate chamber (220), and the communication path (222) includes an arc-shaped part (224) which surrounds at least a part of an outer circumference of the intermediate chamber (220).
