A hydraulic axial pump or hydraulic axially motor with a device for reduction of pressure pulsations

摘要

A hydraulic axial pump or hydraulic motor with axially:a cylinder block (6, 106), which has a plurality of cylinder bores, which are formed around a pivot shaft, and which is designed on a valve plate (7, 107) with a high pressure side connection and a low-pressure connection to slide;a swash plate with a tendency for controlling a - and forth movement amount of a piston in the interior of each cylinder bore;a connecting hole (41 - 1 to 41 - 8), which in the cylinder block (6, 106) is formed and from the cylinder bore to the valve plate (7, 107) is oriented towards;a connection terminal (31) on the side of the upper dead center, which in the valve plate (7, 107) and, in a eindämmbereich is formed on the side of the upper dead center as a region between one end of a valve plates intake connection, and one end of a valve plates delivery connection to the side of the upper dead center is formed;a connection terminal (32) on the side of the lower dead center, which in the valve plate (7, 107) and is designed in a eindämmbereich on the side of the lower dead center as a different region between the end of the valve plates intake connection, and the end of the valve plates delivery connection to the side of the lower dead center is formed; anda radical pressure regeneration circuit (30) for connecting of the connection (31) on the side of the upper dead center to the connection (32) on the side of the lower dead center, ..
