Telescopic pipe assembly
Telescopic pipe assembly for a hydraulic power unit. The telescopic pipe assembly includes, in one example, a first pipe including multiple indents or recesses that are positioned along a portion of the first pipe and a second pipe including an alignment opening, where the first pipe is axially moveable in relation to the second pipe and where the alignment opening is configured to align with each of the multiple indents or recesses in multiple axial positions. The telescopic pipe assembly further includes an attachment device configured to extend through the alignment opening and user-selectably mate with one of the multiple indents or recesses to fix an axial position of the first pipe in relation to the second pipe.
1. A telescopic pipe assembly in a hydraulic power unit, comprising:
a first pipe comprising a plurality of indents or recesses that are positioned along a portion of the first pipe;
a second pipe comprising an alignment opening, wherein the first pipe is axially moveable in relation to the second pipe and wherein the alignment opening is configured to align with each of the plurality of indents or recesses in multiple axial positions; and
an attachment device configured to extend through the alignment opening and user-selectably mate with one of the plurality of indents or recesses to fix an axial position of the first pipe in relation to the second pipe.
2. The telescopic pipe assembly of claim 1 , wherein the plurality of indents are aligned along an axis which is parallel to a central axis of a section of the first pipe.
3. The telescopic pipe assembly of claim 1 , further comprising a seal positioned at an interface between the first pipe and the second pipe.
4. The telescopic pipe assembly of claim 1 , wherein the attachment device is a screw that threadingly engages threads which circumferentially surround the alignment opening.
5. The telescopic pipe assembly of claim 1 , wherein the attachment device is a hooked apparatus that includes:
an extension that mates with the alignment opening and the plurality of indents or recesses; and
a support member that is directly coupled to the extension and a base which is coupled to the second pipe.
6. The telescopic pipe assembly of claim 5 , wherein the support member is flexible.
7. The telescopic pipe assembly of claim 1 , wherein the first pipe is straight.
8. The telescopic pipe assembly of claim 1 , wherein the first pipe includes an angled bend.
9. The telescopic pipe assembly of claim 1 , further comprising an oil filter mated with an upstream end of the second pipe.
10. The telescopic pipe assembly of claim 1 , wherein the second pipe includes a threaded extension that threadingly engages a threaded section of the attachment device.
11. A hydraulic power unit, comprising:
a telescopic suction pipe assembly comprising:
a first pipe comprising a plurality of indents or recesses that are positioned along a portion of the first pipe;
a second pipe comprising an alignment opening, wherein the first pipe is axially moveable in relation to the second pipe and wherein the alignment opening is configured to align with each of the plurality of indents or recesses in multiple axial positions;
an attachment device configured to extend through the alignment opening and user-selectably mate with one of the plurality of indents or recesses to fix an axial position of the first pipe in relation to the second pipe; and
a filter coupled to an upstream end of the second pipe;
a tank fluidly coupled the filter; and
a pump fluidly coupled to a downstream end of the first pipe.
12. The hydraulic power unit of claim 11 , wherein the attachment device is a threaded screw or a hooked apparatus.
13. The hydraulic power unit of claim 11 , further comprising a seal positioned at an interface between the first pipe and the second pipe.
14. The hydraulic power unit of claim 11 , wherein:
the plurality of indents are aligned along an axis which is parallel to a central axis of a section of the first pipe.
