Abstract

A method of filling at least one fluid housing with fluid is disclosed. The method includes: (a) arranging at least one fluid housing within a sealable vessel containing a fluid and attached to a vacuum; and (b) activating the vacuum such that air is withdrawn from the sealable vessel and the fluid is drawn into the at least one fluid housing.

First claim

What is claimed is:

1. A method of filling at least one fluid housing with fluid, the method comprising:
(a) arranging at least one fluid housing within a sealable vessel containing a fluid and attached to a vacuum,
the at least one fluid housing being stationary and upright inside the sealable vessel, such that the at least one fluid housing contacts a base of the sealable vessel,
the at least one fluid housing including at least one radially extending port such that the at least one radially extending port is submerged in the fluid, and
the at least one fluid housing is at least one of: (i) a single feed hydraulic lash adjuster; (ii) a dual feed hydraulic lash adjuster; (iii) a switching roller tappet; or (iv) a bucket tappet; and

(b) activating the vacuum such that air is withdrawn from the sealable vessel and the fluid is drawn into the at least one fluid housing.

2. The method of claim 1 , wherein a pressure within the sealable vessel during step (b) is less than or equal to 1.5 millibar.

3. The method of claim 1 , wherein the at least one fluid housing is completely submerged in the fluid during step (a).

4. The method of claim 1 , wherein the at least one fluid housing is partially submerged in the fluid during step (a).

5. The method of claim 1 , wherein the at least one fluid housing includes a plurality of fluid housings each arranged within the sealable vessel.

6. The method of claim 1 , wherein the vacuum is actuated for at least 90 seconds during step (b).

7. The method of claim 1 , wherein the method further comprising:
(c) deactivating the vacuum and allowing pressure within the sealable vessel to reach atmospheric pressure, and
(d) reactivating the vacuum after step (c) to draw more fluid into the at least one fluid housing.

8. The method of claim 1 , wherein the fluid is at least 120 degrees Fahrenheit.

9. The method of claim 1 , further comprising applying ultrasonic vibration to the sealable vessel during step (b).

10. The method of claim 1 , further comprising attaching an ultrasonic transducer or actuator to the sealable vessel.

11. The method of claim 1 , wherein the fluid housing includes at least one of: (i) a high-pressure chamber; (ii) a low-pressure reservoir; or (iii) a switching fluid chamber.

12. A method of filling at least one fluid housing, the method comprising:
(a) arranging at least one fluid housing including a radially extending port within a sealable vessel containing a fluid, such that the radially extending port is submerged in the fluid,
the at least one fluid housing being stationary and upright inside the sealable vessel, such that the at least one fluid housing contacts a base of the sealable vessel,
the at least one fluid housing is at least one of: (i) a single feed hydraulic lash adjuster; (ii) a dual feed hydraulic lash adjuster; (iii) a switching roller tappet; or (iv) a bucket tappet, and

attaching the sealable vessel to a vacuum; and
(b) activating the vacuum such that air is withdrawn from an interior of the at least one fluid housing and the fluid is drawn into the at least one fluid housing.

13. The method of claim 12 , wherein the fluid is at least 120 degrees Fahrenheit.

14. The method of claim 12 , wherein further comprising applying ultrasonic vibrations to the sealable vessel during step (b).

15. The method of claim 12 , wherein the vacuum is actuated for at least 90 seconds during step (b).

16. The method of claim 12 , further comprising applying ultrasonic vibrations to the sealable vessel during step (b).

17. The method of claim 12 , further comprising:
(c) deactivating the vacuum and allowing pressure within the sealable vessel to reach atmospheric pressure, and
(d) reactivating the vacuum after step (c) to draw more fluid into the at least one fluid housing.

18. The method of claim 1 , wherein the base of the sealable vessel is magnetic and configured to hold the at least one fluid housing upright and stationary.
