Description

VENTURI-TYPE LIQUID PUMP

BACKGROUND OF THE INVENTION

Technical Field

[0001] This invention relates generally to a venturi-type liquid pump used to move a body of liquid from one area to another area and more particularly to the use of a liquid in a liquid-powered venturi-type pump to safely and efficiently remove standing liquid from its current location to a more desirable location.

State of the Art

[0002] Swimming pools, swimming pool covers, above-ground pools, hot tubs, ponds, aquariums, flooded basements and other areas that retain relatively small bodies of liquid often need to be drained before they are cleaned, serviced, repaired, restored, or relocated as the case might be. Devices used to remove liquid from these areas are known in the art. Nevertheless, these conventional devices are inefficient, produce unwanted side-effects, and create undesired hazards.

[0003] Conventional pumps used to remove stationary bodies of liquid often require an electric or gasoline-powered power source to supply the power necessary to produce the pumping action that removes the liquid. Consequently, these pumps are not cost-effective, in that they consume expensive resources to operate. Further, in addition to the costs for electricity and fuel, it is expensive to maintain the moving parts of these conventional devices. For instance, the moving parts of the engine need be serviced and inspected by trained technicians before being operated to ensure proper function. Moreover, these moving parts must be maintained in operating condition even when not in use in order to function properly when needed. Also, over time and under normal operating conditions, the moving parts eventually wear out and need to be replaced. In some instances, overheating and/or overuse can require additional repair and expense. [0004] Aside from the costs to operate these conventional devices, the moving parts of these devices frequently create unwanted noise and or pollution. Both electric-powered pumps and gasoline -powered pumps require motors to operate and thus produce noise. The resulting noise can be inconvenient, and with extended use can be irritating and even annoying. In addition to the noise, gasoline-powered pumps pollute the surrounding environment with their resulting exhaust fumes.

[0005] Many of these conventional devices create additional environmental hazards. Various electric-powered pumps require that they be immersed in the very liquid they are meant to remove in order to perform their intended operation. Thus, these electric-powered pumps may potentially short-circuit in the body of liquid they are meant to remove and thus ruin the pump and create a dangerous electric shock in the liquid. Likewise, gasoline-powered pumps may spring a leak in the gas line and pollute the ground, near the liquid to be removed, upon which they stand, or even the liquid itself.

[0006] These conventional devices also pose undesired functional problems. For example, because the inlet, into which the liquid to be removed enters the device and is pumped out, on many conventional devices is located above the bottom of the body of liquid, many of these conventional devices cannot remove substantially all of the liquid that they are meant to remove. In addition, the conventional devices that contain electric-powered or gasoline -powered motors may be too heavy for the weakest users to use. In other words, these devices may be too heavy or cumbersome for all users to effectively operate. Moreover, in some cases, it may not be possible at all for any user to move these conventional devices if they are permanently fixed above the body of liquid they are to remove.

[0007] Therefore, there is a need in the art for a cost-effective, productive, safe, and light-weight device capable of removing relatively small bodies of liquid from areas in which undesired liquid has accumulated. The present invention satisfies these needs, in addition to other related advantages. DISCLOSURE OF THE INVENTION

[0008] The present disclosure relates to a venturi-type pump comprising a supply line having a front end and a rear end, wherein the front end of the supply line includes a connector for connecting a supply of pressurized liquid to the supply line and the rear end of the supply line includes a nozzle having an exit orifice through which the pressurized liquid exits the supply line; and a suction line having a first end and a second end, wherein the suction line is positioned in relation to the supply line to define a gap between the exit orifice and the first end such that the pressurized liquid exiting the exit orifice traverses the gap and entrains a second liquid within the gap before entering the first end of the suction line together with the entrained second liquid.

[0009] An aspect may include the venturi-type pump wherein the nozzle is a tapered nozzle having a first tapered portion and a second tapered portion, wherein the first tapered portion tapers toward the second tapered portion and the second tapered portion tapers toward the rear end, the first tapered portion being tapered at an angle greater than the tapered angle of the second tapered portion and the second tapered portion defining the exit orifice.

[0010] Another aspect may include the venturi-type pump wherein the supply line and the suction line are hollow and cylindrical in shape. The suction line is connected to the supply line in parallel along a single line in an axial direction of the supply line. Such a configuration allows the aforementioned gap between the supply line and the suction line to be as open as structurally possible. In other words, the supply line and the suction line are connected such that the gap is sufficiently structurally supported while having the fewest number of impediments in the gap.

[0011] Another aspect may include the venturi-type pump wherein the gap is capable of resting on the bottom floor of the body of water so as to allow substantially all of the body of water to be removed by the operation of the venturi-type pump. [0012] Another aspect may include the venturi-type pump further comprising a concave portion in the suction line, wherein the concave portion defines a venturi and the concave portion is positioned in an initial section of the suction line.

[0013] Another aspect may include the venturi-type pump wherein the structure of the nozzle in the supply line decreases the pressure in the nozzle of the supply line, which consequently increases the velocity of the liquid in the nozzle due to the venturi effect, such that the liquid exiting the exit orifice in the nozzle exits in a high-velocity liquid stream. The increased velocity of the liquid stream creates a vacuum effect in the gap, due to Bernoulli's Principle, as the high- velocity liquid stream traverses the gap and enters the suction line such that the standing liquid in the gap enters the suction line along with the liquid stream.

[0014] Another aspect may include the venturi-type pump wherein the gap is sufficiently large to allow a flow rate of liquid that exits the suction line to be greater than a flow rate of liquid that enters the supply line.

[0015] Another aspect may include the venturi-type pump wherein the diameter of the exit orifice is of a sufficient size to permit the high- velocity liquid stream to exit the exit orifice at low volume, whereas the liquid exiting the second end of the suction line exits at a relatively high-volume.

[0016] Another aspect may include the venturi-type pump wherein the radial circumferential wall thickness of the supply line and the suction line are sufficient to withstand the pressure within the respective lines.

[0017] Another aspect may include the venturi-type pump wherein the front end of the supply line and the second end of the suction line are structurally configured to detachably receive connecting hoses that may be used to supply and remove water, respectively. [0018] Another aspect may include the venturi-type pump wherein the front end of the supply line is structured to be a quick snap connector for connecting to a high- pressure supply of liquid and the second end of the suction line is structured to loosely receive an end of any hose-like tubing.

[0019] Another aspect may include the venturi-type pump wherein the diameter of the front end of the supply line is smaller than the diameter of the second end of the suction line.

[0020] Another aspect may include the venturi-type pump wherein the front end of the supply line comprising the quick snap connector is positioned at an angle relative to a remaining portion of the supply line or the second end of the suction line, such that connecting the quick snap connector to the high-pressure supply of liquid does not interfere with connecting the second end of the suction line to the end of the hose-like tubing.

[0021] The foregoing and other features and advantages of the present disclosure will be apparent from the following more detailed description of the particular embodiments of the invention, as illustrated in the accompanying drawings.

DETAILED DESCRIPTION OF EMBODIMENTS OF THE INVENTION

[0030] As discussed above, embodiments of the present invention relate to a venturi-type liquid pump used to move a body of liquid from one area to another area and more particularly to the use of a liquid in a liquid-powered venturi-type pump to safely and efficiently remove standing liquid from its current location to a more desirable location.

[0031] As shown in FIG. 1, particular embodiments include a venturi-type pump 10. The venturi-type pump 10 includes a supply line 20, a suction line 60, and an gap 40 between the supply line 20 and the suction line 60.

[0032] The supply line 20 is a hollow cylindrical pipe-type structure and includes a front end 22 and a rear end 32. The supply line 20 is structured to receive a high- pressure supply of liquid (not shown) at the front end 22 and subsequently channel the supply of liquid from the front end 22 through the hollow supply line 20 to the rear end 32, where the supply of liquid exits the supply line 20. The supply line 20 includes radial walls that are sufficiently thick to hold the pressurized liquid as well as sustain the variable pressures created by the liquid flowing through the supply line 20.

[0033] As shown in FIG. 1, the supply line 20 further includes an initial angled portion 26, beginning from the front end 22 and terminating at an intersection 27. The initial angled portion 26 includes a connecting portion 24 that is structured to receive the high-pressure supply of liquid from a connecting hose (not shown). The initial angled portion 26 is angled with respect to a main body portion 28 of the supply line 20. The initial angled portion 26 ends at the intersection 27, where the initial angled portion 26 meets the main body portion 28. The main body portion 28 extends linearly until the main body portion 28 reaches a curvature portion 30 of the supply line 20. The curvature portion 30 is approximately a 180° curve in the supply line 20 that terminates at a nozzle portion 33. The nozzle portion 33 terminates at the rear end 32 of the supply line 20. The nozzle portion 33 will be described in further detail below. [0034] As shown in FIG. 1, the diameter of the supply line 20 is uniform along the length of the main body portion 28 and the curvature portion 30. However, the diameter of the connecting portion 24 of the initial angled portion 26 is smaller than the diameter of the main body portion 28. This smaller diameter permits the connecting portion 24 to connect with the high-pressure supply of liquid.

[0035] Moreover, the outer circumferential portion of the connecting portion 24 may be structurally configured to receive the corresponding component of

conventional high-pressure liquid supply coupling lines that are known in the art. In other words, the connecting portion 24 may be structured to be one of the

corresponding components of a high-pressure coupling device that comprises known conventional high-pressure liquid supply coupling lines. In addition, the structure of the outer circumferential portion of the connecting portion 24 could vary to incorporate the structural configuration of other known, or even later developed, high- pressure hose connectors.

[0036] The initial angled portion 26 allows the connecting portion 24 to connect to the high-pressure supply of liquid without structurally interfering with a larger diameter portion 70 of the suction line 60, which will be described in greater detail below.

[0037] As shown in FIG. 2, the nozzle portion 33 includes a first tapered portion 35 that tapers toward a second tapered portion 37. The first tapered portion 35 has an initial diameter at an initial point 34 that is equal to the diameter of the supply line 20. From the initial point 34, the first tapered portion 35 diminishes in diameter, or tapers, until the first tapered portion 35 meets the second tapered portion 37 at a meeting point 36. From the meeting point 36, the second tapered portion 37 diminishes in diameter, or tapers, until the second tapered portion 37 reaches the rear end 32 of the supply line 20. The taper angle of the first tapered portion 35 is greater than the taper angle of the second tapered portion 37. In other words, the diameter of the first tapered portion 35 diminishes at a greater rate than does the diameter of the second tapered portion 37. [0038] The first tapered portion 35 and the second tapered portion 37 of the nozzle 33 create a venturi effect. In other words, the tapered diameters of the first tapered portion 35 and the second tapered portion 37 cause the pressure of the liquid flowing through the nozzle portion 33 to decrease due to the increased velocity of the liquid flowing through the nozzle portion 33. Thus, the velocity of the liquid increases within the nozzle portion 33 until the liquid flowing through the nozzle portion 33 exits through the exit orifice 39, as shown in FIG. 3. Moreover, whereas the structure of the first tapered portion 35 functions to create more of the venturi effect than the structure of the second tapered portion 37, the structure of the second tapered portion 37 functions to shape the liquid exiting the exit orifice 39 into a uniform high-velocity stream. The effects of the high-velocity stream will be discussed in more detail below.

[0039] As shown in FIG. 1, the suction line 60 is a hollow cylindrical pipe-type structure and includes a first end 62 and a second end 72. The suction line 60 is structured to receive the high- velocity stream exiting from the supply line 20 and subsequently channel the stream from the first end 62 through the hollow suction line 60 to the second end 72, where the liquid exits the suction line 60. The suction line 60 includes radial walls that are sufficiently thick to hold the liquid as well as sustain the variable pressures created by the liquid flowing through the suction line 60.

[0040] The suction line 60 further includes an initial concave section 64. The initial concave section 64 begins at the first end 62 of the suction line 60 and ends at an ending point 65, as shown in FIG. 2, where the diameter of the concave section 64 is equal to the diameter of a main body portion 66 of the suction line 60. The concave section 64 gradually decreases in diameter from the first end 62 to a point of minimal diameter 63, the point of minimal diameter 63 being positioned approximately midway between the first end 62 and the ending point 65. From the point of minimal diameter 63, the diameter of the concave section 64 gradually increases until the ending point 65, where the diameter of the concave section 64 and the diameter of the main body portion 66 are equivalent, as mentioned above. [0041] The diameter of the first end 62 of the concave section 64 is larger than the diameter of the ending point 65 of the concave section 64. The increased diameter at the first end 62 allows the suction line 60 to intake an increased volume of liquid, as will be discussed below. In other embodiments, to adjust the intake of liquid into the suction line 60, the diameter of the first end 62 can be adjusted.

[0042] The main body portion 66 extends linearly until the main body portion 66 reaches the large diameter portion 70 at junction 68. The large diameter portion 70 has a larger diameter than the diameter of the main body portion 66. The large diameter portion 70 extends linearly from the junction 68 to the second end 72. The large diameter portion 70 defines a second exit orifice 74, as shown in FIG. 6, from which the liquid exits the suction line 60.

[0043] The large diameter portion 70 is structured to receive a hose-type tubing (not shown) of various sizes and configurations. Accordingly, the hose-type tubing may be placed around and over the exterior surface of the large diameter portion 70 or, alternatively, the hose-type tubing may be placed entirely within the inner surface of the large diameter portion 70. One of ordinary skill in the art will understand that several methods may be employed to secure or attach the hose-type tubing to the large diameter portion 70. For example, in the case where the hose-type tubing is placed over the exterior surface, the tubing may expand over the exterior surface to be held by friction. Alternatively, in the case where the hose-type tubing is placed within the large diameter portion 70, the tubing may constrict within the inner surface to be held by friction. Moreover, adhesives of all varieties may be employed to detachably connect the hose-type tubing to the large diameter portion 70. Further yet, in other embodiments, the threads on the end of the hose-type tubing may be screwed into the corresponding threads on the large diameter portion 70 (not shown).

[0044] As shown in FIG 1, the supply line 20 and the suction line 60 are positioned such that the main body portion 28 of the supply line 20 and the main body portion 66 of the suction line 60 are substantially parallel to one another. Further, in this configuration, the supply line 20 and the suction line 60 are in contact with one another along a contact line 50, which runs along the length of the main bodies 28 and 66. As such, the supply line 20 and the suction line 60 are connected to each other along the length of the contact line 50. Alternatively, the supply line 20 and the suction line 60 may be attached to each other at various points along the contact line 50. Nevertheless, because the supply line 20 and the suction line 60 are coupled together along the line 50, or at a number of points along the line 50, the structural integrity of the pump is provided. The external and internal forces acting on the pump 10 are supported and sustained by the strong coupling between the respective lines 20 and 60 along the contact line 50. Indeed, the strength of the contact line 50 allows the supply line 20 and the suction line 60 to remain in place with respect to one another to permit the gap 40 to function as explained herein.

[0045] In addition, coupling the supply line 20 and the suction line 60 as described above allows a connecting hose attached to each of the supply line 20 and the suction line 60 to extend from the pump 10 in substantially the same direction. As a result, because the pump 10 thus does not have a connecting hose stemming from each of its ends, or from opposing ends, the pump 10 is able to fit in tighter and smaller areas. Moreover, because the pump 10 thus does not have a connecting hose stemming from each of its ends, the weight of the connecting hoses or the forces acting on the connecting hoses do not act to twist, bend, or otherwise displace the supply line 20 or the suction line 60 from their respective positional relationship with each other. In this way, the structural integrity of the gap 40 is preserved.

[0046] As shown in FIGS. 2, 4, and 5, the positioning of the suction line 60 in relation to the supply line 20 defines the gap 40, mentioned above. Specifically, the suction line 60 is connected to the supply line 20 so as to position the first end 62 of the suction line 60 proximate the rear end 32 of the supply line. Such a configuration allows the high- velocity stream that exits the exit orifice 39 of the supply line 20 to traverse the gap 40 and enter the first end 62 of the suction line 60. The exit orifice 39 is positioned in a cross-sectional center of the supply line 20, such that the high- velocity stream that exits the exit orifice 39 traverses the cross-sectional center of the gap 40 and enters the cross-sectional center of the suction line 60. [0047] The high- velocity stream that traverses the gap 40 creates a vacuum effect in and around the high-velocity stream due to Bernoulli's Principle. Thus, under the condition that the venturi-type pump 10 is immersed, or submerged, in a standing body of liquid, the vacuum effect created by the high-velocity stream causes the standing liquid within and around the gap 40 to entrain with the high- velocity liquid traversing the gap 40, such that the standing liquid and the high-velocity stream enter the first end 62 together. In fact, the structure of the venturi-type pump 10 described above permits the volume of standing liquid that enters the first end 62 to be substantially greater than the volume of high- velocity liquid that enters the first end 62. Accordingly, the liquid that flows through the suction line 60 and exits the second exit orifice 76 is comprised primarily of the standing liquid and not the high-velocity stream.

[0048] In addition, the concave portion 64 creates a venturi effect on the entrained liquid entering the first end 62. As a result, the entrained liquid initially increases in velocity as it flows into the suction line 60, which, together with the vacuum effect described above, increases the volume of liquid that flows into and through the suction line 60.

[0049] FIGS. 4 and 5 further show that attaching the suction line 60 in parallel with the supply line 20 along the contact line 50 allows the greatest volume of water to enter into the first end 62. By connecting the supply line 20 to the suction line 60 along the contact line 50, there is no need to place additional structural elements across the gap 40 to secure the supply line 20 to the suction line 60. Moreover, the circular shape of the supply line 20 and the suction line 60 permit the efficient flow of liquid over and around their outer surfaces, respectively. Further, the tapered shape of the nozzle 33 also allows more of the standing water to fill the gap 40 to be entrained by the high velocity stream. As a result, the gap 40 can be relatively narrow, placing the exit orifice 39 relatively close to the first end 62, and yet the pump 10 can still entrain the requisite amount of standing water from within the gap 40. As a result, the structural configuration of the venturi-type pump 10, as shown in FIGS. 4 and 5, permits the gap 40 to be open and free-flowing. [0050] The above-described structural configuration also permits the venturi-type pump 10 to remove substantially all of the standing liquid it is meant to remove. The venturi-type pump 10 is structured to allow the first end 62 to rest flat against a bottom surface of the standing body of water. Because the first end 62 is flat against the bottom surface, the venturi-type pump 10 is capable of removing the standing liquid down to the bottom surface against which the first end 62 rests.

[0051 ] As shown in FIG. 7, broken- line arrows show the flow of liquid in the pump 10. Liquid flows through the supply line 20 and changes direction as it rounds about the curvature portion 30 at the latter end of the supply line 20. The liquid then enters the nozzle 33 and increases in velocity until it exits the nozzle at the exit orifice 39 as a high- velocity stream. Once exited, the high- velocity stream crosses the gap 40 and enters the first end 62 of the suction line 60. As the high- velocity stream crosses the gap 40, it entrains the standing liquid in and around the gap 40. Solid-line arrows show the flow of standing liquid surrounding the gap 40 as it is entrained by the high- velocity stream and enters the suction line 60 together with the high -velocity stream.

[0052] As shown in FIG. 8, the venturi-type pump 10 can be utilized effectively to drain standing bodies of liquid of any shape and size. Indeed, the pump 10 may form part of a liquid-removal system in which a pressurized supply of water 80, or other liquid, is releasably coupled to the front end of the supply line 20. The pressurized supply of water 80 provides the pressurized water, or other liquid, to the pump 10 and drives the flow of liquid through the pump 10. The pump 10 is immersed in a standing body of liquid. The standing body of liquid can be water, or it can be any other type of liquid. Indeed, the liquid supplied in the pressurized supply need not be of the same type as the standing body of liquid. As the pressurized flow of water exits the exit orifice 39 in a high- velocity stream, the flow of water entrains any liquid, as mentioned above, standing in the gap 40. The entrained liquid and the high- velocity stream both enter the suction line at the first end 62 and exit the suction line at second end 72. A drain hose 82 is releasably coupled to the second end 72 and facilitates the draining of the entrained liquid and the high-velocity stream from the pump 10. In this way, the pump 10 is part of a larger system that effectively and efficiently removes standing bodies of liquid. This is accomplished without the need for gasoline-powered, propane-powered, or other fuel-powered motors to provide the pumping or siphoning action to remove the standing body of liquid. Indeed, the pump 10 does not require any moving parts whatsoever. In addition, the pump 10 does not require any external electric power source to properly function. The pump 10 simply operates by being immersed in a body of liquid and receiving and channeling a pressurized supply of water that functions to remove the body of liquid from its location.

[0053] The components defining the above-described venturi-type pump 10 may be formed of any of many different types of materials or combinations thereof that can readily be formed into shaped objects provided that the components selected are consistent with the intended operation of a venturi-type pump. For example, the components may be formed of: rubbers (synthetic and/or natural) and/or other like materials; glasses (such as fiberglass) carbon-fiber, aramid-fiber, any combination thereof, and/or other like materials; polymers such as thermoplastics (such as ABS, Fluoropolymers, Polyacetal, Polyamide; Polycarbonate, Polyethylene, Polysulfone, and/or the like), thermosets (such as Epoxy, Phenolic Resin, Polyimide, Polyurethane, Silicone, and/or the like), any combination thereof, and/or other like materials;

composites and/or other like materials; metals, such as zinc, magnesium, titanium, copper, iron, steel, carbon steel, alloy steel, tool steel, stainless steel, aluminum, any combination thereof, and/or other like materials; alloys, such as aluminum alloy, titanium alloy, magnesium alloy, copper alloy, any combination thereof, and/or other like materials; any other suitable material; and/or any combination thereof.

[0054] Furthermore, the components defining the above-described venturi-type pump 10 may be purchased pre-manufactured or manufactured separately and then assembled together. However, any or all of the components may be manufactured simultaneously and integrally joined with one another. Manufacture of these components separately or simultaneously may involve extrusion, pultrusion, vacuum forming, injection molding, blow molding, resin transfer molding, casting, forging, cold rolling, milling, drilling, reaming, turning, grinding, stamping, cutting, bending, welding, soldering, hardening, riveting, punching, plating, and/or the like. If any of the components are manufactured separately, they may then be coupled with one another in any manner, such as with adhesive, a weld, a fastener (e.g. a bolt, a nut, a screw, a nail, a rivet, a pin, and/or the like), wiring, any combination thereof, and/or the like for example, depending on, among other considerations, the particular material forming the components. Other possible steps might include sand blasting, polishing, powder coating, zinc plating, anodizing, hard anodizing, and/or painting the components for example.

13. The venturi-type pump of claim 1, wherein the structure of the suction line in relation to the supply line allows the first end of the suction line to contact a bottom surface of a body of water in which the pump is submerged so that the pump can remove the body of water.

14. The venturi-type pump of claim 1, wherein the radial circumferential wall thickness of the supply line and the suction line are sufficient to withstand the pressure within the respective lines.

15. A venturi-type pump, the pump comprising:

a cylindrical supply line having a terminal end;

a cylindrical suction line having an initial end, the suction line being coupled in parallel to the supply line along an axial length of the supply line;

a gap between the terminal end of the supply line and the initial end of the suction line;

a nozzle defined by the terminal end of the supply line;

a concave section in the suction line, the concave section beginning at the initial end of the suction line;

wherein the supply line receives a pressurized flow of liquid that flows through the supply line, and

further wherein the gap is configured such that the flow of pressurized liquid exits the supply line at the terminal end and, under the condition that the pump is submerged in a body of liquid, entrains the body of liquid proximate the gap as the pressurized liquid traverses the gap, and

further wherein the entrained liquid and the pressurized liquid enter the initial end of the suction line together.

16. The venturi-type pump of claim 15, wherein the terminal end of the supply line defines an exit orifice, the exit orifice being structured to shape the pressurized liquid exiting the terminal end into a pressurized stream and the exit orifice being positioned in substantially the center of a cross-section of the supply line, such that the pressurized stream that traverses the gap enters the initial end of the suction line in a central cross-sectional portion of the suction line, whereas the entrained liquid enters the initial end of the suction line in and around all sides of the pressurized stream.

17. The venturi-type pump of claim 15, wherein a direction of the liquid flowing through a portion of the supply line is opposite a direction of the liquid flowing through the suction line.

18. The venturi-type pump of claim 15, the nozzle further comprising:

a first tapered portion; and

a second tapered portion,

wherein the first tapered portion tapers toward the second tapered portion and the second tapered portion tapers toward the terminal end of the supply line, the first tapered portion being tapered at an angle greater than a tapered angle of the second tapered portion.

19. The venturi-type pump of claim 15, wherein a volume of liquid that exits the suction line is greater than a volume of liquid that enters the supply line.

20. A liquid-removal system, the system comprising:

a pressurized supply of liquid;

the venturi-type pump of claim 1 immersed in a standing body of liquid; and a drain hose,

wherein the pressurized supply of liquid is releasably coupled to the supply line and provides the pressurized flow of water through the pump and the drain hose is releasably coupled to the suction line and drains the flow of liquid from the suction line.
