ABSTRACT:
In the manufacture of vane type pumps, particularly for booster steering systems, precision assembly between the flow directing plate, sometimes referred to as a cheek plate, control plate, etc., and the cam ring is provided economically by die casting either or both components and effecting a pair of die cast tapering flat sided locating bores. One bore is elongated to allow for inaccuracies while the other is box-like in cross section. Locator pins secured in reamed bores are force fitted into the cast bores wherein the box-like bore which is dimensioned to fit a pin determines the rotational center of the components with respect to each other for exact relative positioning. The position is fixed by a pin in the elongated bore which pin can be accommodated in the elongation to compensate for spacing errors of the bores.
