Abstract

A manifold for a pump is configured to connect to a jacket to form a reservoir and to connect to at least one pumping mechanism disposed within the reservoir. The manifold includes a first side including a first side surface configured to face the reservoir and a second side including a second side surface. The manifold also includes a bypass passage, at least one push rod guide bore extending through the first side surface and the second side surface, and a leakage passage fluidly connecting the at least one push rod guide bore to an outlet disposed outside the first side surface. The manifold further includes a discharge passage including at least one inlet disposed in the first side surface, and the at least one inlet is configured to receive fluid pumped by the at least one pumping mechanism.

First claim

What is claimed is:

1. A manifold for a pump, the manifold being configured to connect to a jacket to form a reservoir and to connect to at least one pumping mechanism disposed within the reservoir, the manifold comprising:
a first side including a first side surface configured to face the reservoir;
a second side opposite the first side, the second side including a second side surface;
a plurality of push rod guide bores extending through the first side surface and the second side surface;
a leakage passage including a plurality of connecting branches fluidly connecting each of the plurality of push rod guide bores to an outlet branch including an outlet disposed outside the first side surface;
a bypass passage including an inlet disposed in the first side surface, the bypass passage further including an outlet disposed outside the first side surface; and
a discharge passage including at least one inlet disposed in the first side surface, the at least one inlet of the discharge passage configured to fluidly connect to the at least one pumping mechanism to receive fluid pumped by the at least one pumping mechanism, the discharge passage further including an outlet disposed outside the first side surface,
wherein the connecting branches of the leakage passage and the push rod guide bores form a loop, and
wherein each connecting branch of the leakage passage extends between a respective pair of the push rod guide bores, each connecting branch including two linear portions, each of the linear portions having a first end and a second end, the first ends of the two linear portions intersecting a respective one of the pair of the push rod guide bores, the second ends of the two linear portions connecting to each other to form an apex.

2. The manifold of claim 1 , wherein the second side includes a base, the base forming the second side surface; and the first side includes a raised portion extending from the base, the raised portion forming the first side surface facing away from the base and being configured to be inserted into the jacket.

3. The manifold of claim 2 , further including:
an inlet passage including an inlet disposed outside the first side surface, the inlet passage further including an outlet disposed in the first side surface;
wherein the outlet of the inlet passage is disposed adjacent a center of the raised portion.

4. The manifold of claim 3 , wherein:
the at least one inlet of the discharge passage includes a plurality of inlets of the discharge passage disposed farther from the center of the raised portion than the outlet of the inlet passage, and the at least one pumping mechanism includes a plurality of pumping mechanisms, each of the plurality of the inlets of the discharge passage corresponding to one of the plurality of the pumping mechanisms; and
the discharge passage further includes a plurality of connecting branches and an outlet branch, the outlet branch of the discharge passage including the outlet, the connecting branches of the discharge passage fluidly connecting each inlet of the discharge passage in parallel to the outlet branch of the discharge passage.

5. The manifold of claim 4 , wherein each connecting branch of the discharge passage is generally perpendicular to the outlet branch of the discharge passage when viewed from at least one of the first side or the second side.

6. The manifold of claim 3 , wherein the raised portion includes a recess near the center of the raised portion, the outlet of the inlet passage being disposed in the recess.

7. The manifold of claim 2 , further including:
a peripheral surface extending between the first and second sides;
wherein the base includes a flange forming the peripheral surface, the flange including at least one mounting bore extending through the flange and configured to receive at least one fastener.

8. The manifold of claim 7 , wherein:
the at least one mounting bore includes a plurality of mounting bores disposed around a periphery of the flange;
the outlet of the leakage passage, the outlet of the bypass passage, and the outlet of the discharge passage are disposed on the peripheral surface; and
the leakage passage, the bypass passage, and the discharge passage are disposed between different pairs of the plurality of mounting bores.

9. The manifold of claim 1 , wherein the plurality of the push rod guide bores and the connecting branches of the leakage passage are disposed around the at least one inlet of the discharge passage.

10. The manifold of claim 1 , wherein the inlet of the bypass passage is disposed outside the loop.

11. A manifold for a pump, the manifold being configured to connect to a jacket to form a reservoir and to connect to at least one pumping mechanism disposed within the reservoir, the manifold comprising:
a first side including a first side surface configured to face the reservoir;
a second side opposite the first side, the second side including a second side surface;
an inlet passage including an inlet disposed outside the first side surface, the inlet passage further including an outlet disposed in the first side surface;
a plurality of push rod guide bores each extending through the first side surface and the second side surface;
a leakage passage including a plurality of connecting branches fluidly connecting the plurality of push rod guide bores, at least one of the connecting branches being fluidly connected to an outlet branch having an outlet disposed outside the first side surface;
a bypass passage including an inlet disposed in the first side surface, the bypass passage further including an outlet disposed outside the first side surface; and
a discharge passage including a plurality of inlets disposed in the first side surface, the plurality of inlets of the discharge passage being configured to fluidly connect to the plurality of pumping mechanisms to receive fluid pumped by the plurality of pumping mechanisms, and the plurality of inlets being connected in parallel to an outlet branch, the outlet branch of the discharge passage having an outlet disposed outside the first side surface,
wherein the connecting branches of the leakage passage and the push rod guide bores form a loop, and
wherein each connecting branch of the leakage passage extends between a respective pair of the push rod guide bores, each connecting branch including two linear portions, each of the linear portions having a first end and a second end, the first ends of the two linear portions intersecting a respective one of the pair of the push rod guide bores, the second ends of the two linear portions connecting to each other to form an apex.

12. The manifold of claim 11 , wherein the discharge passage further includes a plurality of connecting branches fluidly connecting each inlet of the discharge passage in parallel to the outlet branch of the discharge passage.

13. The manifold of claim 11 , wherein the outlet branch of the leakage passage fluidly connects to at least one of the connecting branches of the leakage passage in the loop.

14. A pump comprising:
a reservoir configured to receive a fluid from a storage tank;
