2. The hydraulic lash adjuster assembly of claim 1 , wherein the at least one first tab and the at least one second tab are arranged circumferentially aligned with each other on radially opposite faces of the circular body.
3. The hydraulic lash adjuster assembly of claim 1 , wherein the at least one first tab and the at least one second tab are arranged circumferentially offset from each other on radially opposite faces of the circular body.
4. The hydraulic lash adjuster assembly of claim 1 , wherein the clip is formed from a polymeric material.
5. The hydraulic lash adjuster assembly of claim 1 , wherein the clip is formed from a stamped metal.
6. The hydraulic lash adjuster assembly of claim 1 , wherein the clip is formed from a stamped steel.
7. The hydraulic lash adjuster assembly of claim 1 , wherein the at least one first tab is formed from an elastically deformable material.
8. The hydraulic lash adjuster assembly of claim 1 , wherein the at least one first tab includes two of the first tabs, and one of the first tabs engages a first portion of the at least one hydraulic fluid gallery, and the other of the first tabs engages a second portion of the at least one hydraulic fluid gallery on an opposite side of the at least one hydraulic fluid gallery from the first portion of the at least one hydraulic fluid gallery.
9. The hydraulic lash adjuster assembly of claim 1 , wherein the at least one first tab and the at least one second tab have the same dimensions.
10. A hydraulic lash adjuster assembly comprising:
a housing positioned including an annular body that includes a port on a radially outer wall of the housing;
a plunger arranged within the housing that is axially displaceable therein; and
a clip including a circular body and at least one first tab extending radially outwardly that engages at least one hydraulic fluid gallery formed on a cylinder head, and at least one second tab extending radially inwardly that engages the port.
11. A hydraulic lash adjuster arrangement comprising:
a cylinder head including a bore and at least one hydraulic fluid gallery; and
a hydraulic lash adjuster assembly including:
a housing positioned in the bore of the cylinder head including an annular body that includes a port on a radially outer wall of the housing;
a plunger arranged within the housing that is axially displaceable therein; and
a clip including a circular body and at least one first tab extending radially outwardly and at least one second tab extending radially inwardly, wherein the port is located within an annular groove on the radially outer wall of the housing, and the clip is positioned within the annular groove.
12. The hydraulic lash adjuster assembly of claim 11 , wherein the at least one first tab and the at least one second tab are arranged circumferentially aligned with each other on radially opposite faces of the circular body.
13. The hydraulic lash adjuster assembly of claim 11 , wherein the at least one first tab and the at least one second tab are arranged circumferentially offset from each other on radially opposite faces of the circular body.
14. The hydraulic lash adjuster assembly of claim 11 , wherein the clip is formed from a polymeric material.
15. The hydraulic lash adjuster assembly of claim 11 , wherein the clip is formed from a stamped metal.
16. The hydraulic lash adjuster assembly of claim 11 , wherein the clip is formed from a stamped steel.
17. The hydraulic lash adjuster assembly of claim 11 , wherein the at least one first tab is formed from an elastically deformable material.
18. The hydraulic lash adjuster assembly of claim 11 , wherein the at least one first tab and the at least one second tab have the same dimensions.
19. The hydraulic lash adjuster assembly of claim 11 , wherein the at least one first tab includes two of the first tabs, and one of the first tabs engages a first portion of the at least one hydraulic fluid gallery, and the other of the first tabs engages a second portion of the at least one hydraulic fluid gallery on an opposite side of the at least one hydraulic fluid gallery from the first portion of the at least one hydraulic fluid gallery.
