Abstract

An oil reservoir for a variable camshaft phaser, comprising a locking cover including a front surface including a pool, the pool having a plurality of through-bores, a rear surface including a locking pin channel, a radially inward facing surface, and a radially outward facing surface, and an oil reservoir cover secured to the front surface of the locking cover.

First claim

What is claimed is:

1. An oil reservoir for a variable camshaft phaser, comprising:
a locking cover, including:
a front surface including a pool, the pool having a plurality of through-bores;
a rear surface including a locking pin channel;
a radially inward facing surface; and,
a radially outward facing surface; and,

an oil reservoir cover secured to the front surface of the locking cover.

2. The oil reservoir as recited in claim 1 , wherein the locking cover further comprises a recess extending radially outward from the radially inward facing surface.

3. The oil reservoir as recited in claim 1 , wherein the locking cover further comprises a first plurality of holes operatively arranged to attach the locking cover to the variable camshaft phaser via a plurality of bolts.

4. The oil reservoir as recited in claim 3 , wherein the locking cover further comprises a plurality of counter-bores, and each of the first plurality of holes comprises one of the plurality of counter-bores.

5. The oil reservoir as recited in claim 4 , wherein the oil reservoir cover comprises a plurality of depressions extending in a first axial direction, the plurality of depressions operatively arranged to engage the plurality of counter-bores.

6. The oil reservoir as recited in claim 5 , wherein the oil reservoir cover further comprises a second plurality of holes operatively arranged to align with the first plurality of holes and attach the oil reservoir cover to the variable camshaft phaser via the plurality of bolts.

7. The oil reservoir as recited in claim 6 , wherein the oil reservoir cover comprises a frusto-conical surface extending in a second axial direction, opposite the first axial direction.

8. The oil reservoir as recited in claim 7 , wherein the oil reservoir cover is made of thin sheet metal.

9. An oil reservoir for a variable camshaft phaser, comprising:
a locking cover, including:
a front surface including a pool, the pool having a plurality of through-bores;
a rear surface including a locking pin channel;
a radially inward facing surface including a recess extending radially outward therefrom; and,
a radially outward facing surface; and,

an oil reservoir cover secured to the front surface of the locking cover.

10. The oil reservoir as recited in claim 9 , wherein the locking cover further comprises a first plurality of holes operatively arranged to attach the locking cover to the variable camshaft phaser via a plurality of bolts.

11. The oil reservoir as recited in claim 10 , wherein the locking cover further comprises a plurality of counter-bores, and each of the first plurality of holes comprises one of the plurality of counter-bores.

12. The oil reservoir as recited in claim 11 , wherein the oil reservoir cover comprises a plurality of depressions extending in a first axial direction, the plurality of depressions operatively arranged to engage the plurality of counter-bores.

13. The oil reservoir as recited in claim 12 , wherein the oil reservoir cover further comprises a second plurality of holes operatively arranged to align with the first plurality of holes and attach the oil reservoir cover to the variable camshaft phaser via the plurality of bolts.

14. The oil reservoir as recited in claim 13 , wherein the oil reservoir cover comprises a frusto-conical surface extending in a second axial direction, opposite the first axial direction.

15. The oil reservoir as recited in claim 14 , wherein the oil reservoir cover is made of thin sheet metal.

16. An oil reservoir for a variable camshaft phaser, comprising:
a locking cover, including:
a front surface including:
a pool having a plurality of through-bores;
a first plurality of holes operatively arranged to attach the locking cover to the variable camshaft phaser using a plurality of bolts;

a rear surface including a locking pin channel;
a radially inward facing surface including a recess extending radially outward therefrom; and,
a radially outward facing surface; and,

an oil reservoir cover secured to the front surface of the locking cover.

17. The oil reservoir as recited in claim 16 , wherein the locking cover further comprises a plurality of counter-bores, and each of the first plurality of holes comprises one of the plurality of counter-bores.

18. The oil reservoir as recited in claim 17 , wherein the oil reservoir cover comprises a plurality of depressions extending in a first axial direction, the plurality of depressions operatively arranged to engage the plurality of counter-bores.

19. The oil reservoir as recited in claim 18 , wherein the oil reservoir cover further comprises a second plurality of holes operatively arranged to align with the first plurality of holes and attach the oil reservoir cover to the variable camshaft phaser via the plurality of bolts.

20. The oil reservoir as recited in claim 19 , wherein the oil reservoir cover comprises a frusto-conical surface extending in a second axial direction, opposite the first axial direction.
