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.

Injector piston with improved seal

A seal assembly includes an annular seal body disposable about a first member and having an axial sealing lip engageable with the radial surface of a second member, first and second circumferential ends and an outer circumferential surface. A plurality of teeth extend outwardly from the outer surface and are spaced circumferentially about a centerline. A first coupler member has teeth disposed between and attached to the teeth of the seal body to form a first attachment interface adjacent to the seal body first end. A second coupler member has teeth disposed between and attached to the teeth of the seal body to form a second attachment interface adjacent to the seal body second end. The first and second coupler members are connected so as to couple the two ends of the seal body and to retain the seal assembly about the first member.

Split V-ring seal assembly

A shield device prevents materials from contacting a seal for a shaft extending outwardly from a housing and displacing a mounted component. The shield device includes an annular disk having opposing first and second radial surfaces and outer and inner circumferential edges, the inner edge defining a bore for receiving the shaft. The disk is coupleable with the shaft so as to be disposed between the component and the housing and is spaced axially above the seal such that the first radial surface faces the seal. The disk has an outside diameter greater than the seal outside diameter and overlaps the seal with the disk outer edge being spaced radially outwardly from the seal to provide a barrier about the seal. Preferably, an annular projection extends axially outwardly from the first, lower radial surface and is disposeable within a circular groove of the housing that extends about the seal.
