A lubricating system that includes a manifold with one or more manifold ports that permit a flow of lubricant through the manifold. The manifold is configured for removable attachment to another manifold such that any number of manifold can be joined together. An ejector is removably attached to the manifold. The ejector has one or more projections configured for insertion into each of the one or more manifold ports in the manifold, such that the ejector is configured to receive the flow of lubricant from the manifold, via the one or more projections, and to discharge lubricant periodically, or at preset intervals, from one or more outlet ports of the ejector. A locking key is disposed between the manifold and ejector. The locking key is configured such that movement of the locking key attaches or detaches the ejector from the manifold.

A piston assembly is for a fluid delivery device, preferably a lubricant injector, the injector having a measuring chamber defined by an inner cylindrical surface and an axial end face, a flow port through the end face, and a central axis extending through the chamber. The piston assembly includes a piston body disposeable within the chamber so as to be linearly displaceable along the central axis. The piston body includes a cylindrical head, the head having first and second axial ends and an outer circumferential surface, and a rod extending axially from the second axial end of the piston head. A seal is coupled with the first axial end of the piston head and has an annular lip sealingly engageable with the chamber inner cylindrical surface and an axial end engageable with the chamber end face.

A lubricant injector includes an injector body having an inlet port fluidly coupleable with a lubricant supply, an outlet port fluidly coupleable with a lubrication point, a piston chamber and a valve chamber. A piston is disposed within the piston chamber and defines a measuring section and an actuating section, the piston being linearly displaceable along an axis through the piston chamber so as to inversely vary the volume of the chamber measuring section and the volume of the chamber actuating section. A valve member disposed within the valve chamber is displaceable along an axis through the valve chamber between a first position, at which the inlet port is fluidly coupled with the piston chamber actuating and measuring sections, and a second position at which the inlet port is fluidly coupled with the piston chamber actuating section and the outlet port is fluidly coupled with the piston chamber measuring section.

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.
