Abstract
A mechanism for converting rotary motion in rectilinear to and fro comprising and hinged in the housing of a crosspiece by a prestressed rod and conical bearing. An even number of bearings stacked symmetrically on each side of the center and internal cages are fitted an intermediate bush with the interposition of spacing rings, the thicknesses of the rings being so determined that the pre-stressing force is distributed equally between the bearings and causes the complete take-up of play. The invention is particularly useful in multicylinder pump mechanisms distributed regularly around a shaft and with axial pistons.
