Abstract

A progressive distributor includes a housing block with an inlet bore and outlet bores and first and second metering pistons in first and second piston bores. Each piston defines first and second annular workspaces and delimits first and second metering spaces at the ends of each piston, the first and second piston bores each having a central axis and being disposed one atop the other so that their central axes are parallel to each other and located in a central plane. Switching bores connect the metering spaces of the first metering piston to the workspaces of the second metering piston, and the switching bores are located on opposite sides of the central plane.
