Abstract

A guide element for hydraulic fluid includes a first end surface, a second end surface, and an exterior surface connecting the first end surface to the second end surface. The first end surface includes a first chamfered opening. The second end surface includes a second opening that fluidly communicates with the first opening to define a longitudinal bore that includes a tapered section. The first chamfered opening and the tapered section are configured to guide the hydraulic fluid to facilitate transformation of a turbulent flow of the hydraulic fluid into a laminar flow of the hydraulic fluid.

First claim

What is claimed is:

1. A guide element for hydraulic fluid, comprising:
a first end surface, a second end surface, and an exterior surface connecting the first end surface to the second end surface, wherein
the first end surface includes a first chamfered opening,
the second end surface includes a second opening that fluidly communicates with the first chamfered opening to define a longitudinal bore that includes a tapered section,
wherein the first chamfered opening and the tapered section are configured to guide the hydraulic fluid to facilitate transformation of a turbulent flow of the hydraulic fluid into a laminar flow of the hydraulic fluid, and the exterior surface includes:
a head portion that is adjacent to the first end surface, and
a threaded shank portion that is between the head portion and the second end surface,
wherein the head portion has a first diameter that is greater than a second diameter of the threaded shank portion.

2. The guide element of claim 1 , wherein
the longitudinal bore further includes a first linear section that is adjacent to the first chamfered opening and a second linear section that is adjacent to the second opening; and
the tapered section is located between the first linear section and the second linear section.

3. The guide element of claim 2 , wherein
the longitudinal bore further includes a third linear section that is located between the tapered section and the second linear section; and
a third diameter of the first linear section and a fourth diameter of the second linear section are greater than a fifth diameter of the third linear section.

4. The guide element of claim 1 , wherein the tapered section has
a third diameter in a range of approximately 8 millimeters to approximately 9 millimeters,
a fourth diameter in a range of approximately 4 millimeters to approximately 5 millimeters, and
a length in a range of approximately 4 millimeters to approximately 7 millimeters.

5. A guide element for fluid, comprising:
a first end surface, a second end surface, and an exterior surface connecting the first end surface to the second end surface, wherein
the first end surface includes a first opening, and
the second end surface includes a second opening that fluidly communicates with the first opening to define a longitudinal bore,
wherein the longitudinal bore includes:
a truncated conical section that is configured to reduce turbulence of the fluid flowing therethrough,
a first cylindrical section that is adjacent to the second opening, and
a second cylindrical section that is between the truncated conical section and the first cylindrical section,
 wherein the first cylindrical section has a first diameter that is greater than a second diameter of the second cylindrical section.

6. The guide element of claim 5 , wherein the longitudinal bore is shaped and sized to facilitate transformation of a turbulent flow of the fluid into a laminar flow of the fluid,
wherein the laminar flow of the fluid has a flow rate in a range of approximately 1.5 liters per minute to approximately 5 liters per minute.

7. The guide element of claim 5 , wherein
the first diameter is in a first range of approximately 8 millimeters to approximately 9 millimeters; and
the second diameter is in a second range of approximately 4 millimeters to approximately 5 millimeters.

8. The guide element of claim 5 , wherein the longitudinal bore further includes a third cylindrical section that extends from the first opening to the truncated conical section.

9. The guide element of claim 8 , wherein a third diameter of the third cylindrical section is in a range of approximately 8 millimeters to approximately 9 millimeters.

10. The guide element of claim 5 , wherein
the first end surface has a first outer diameter; and
the second end surface has a second outer diameter that is less than the first outer diameter.

11. The guide element of claim 10 , wherein
the first outer diameter is in a first range of approximately 14 to approximately 15 millimeters; and
the second outer diameter is in a second range of approximately 11 to approximately 12 millimeters.

12. A guide element for hydraulic fluid, comprising:
a first end surface, a second end surface, and an exterior surface connecting the first end surface to the second end surface, wherein
the first end surface includes a first opening,
the second end surface includes a second opening that fluidly communicates with the first opening to define a longitudinal bore that includes a tapered section,
wherein the tapered section is configured to guide the hydraulic fluid to facilitate transformation of a turbulent flow of the hydraulic fluid into a laminar flow of the hydraulic fluid, and

the exterior surface includes:
a head portion having a first diameter, and
a threaded shank portion having a second diameter that is less than the first diameter.

13. The guide element of claim 12 , wherein the first opening is chamfered to further guide the hydraulic fluid to facilitate the transformation of the turbulent flow of the hydraulic fluid into the laminar flow of the hydraulic fluid.

14. The guide element of claim 12 , wherein the tapered section has a length in a range of approximately 4 millimeters to approximately 7 millimeters.

15. The guide element of claim 12 , wherein
the first opening has a third diameter in a range of approximately 8 millimeters to approximately 9 millimeters, and
