<p>A swashplate hydraulic pump has a number of pistons (1) with hemi-spherical ends which are pressed by springs (3) against a shoe (4) which slides on the surface (5) of the swashplate (6). When the piston is at BDC, its open end and the hole (10) in the shoe (4) are aligned with the inlet port (12) in the swashplate. This port is symmetrical about the diameter which lies along the line of maximum slope of the swashplate. This symmetry of the inlet port enables the pump to operate equally well in either direction of rotation.</p> |
