INVENTOR HENRY E. AVER/YA/V ATTORNEYS MODULAR HYDRAULIC SYSTEM BACKGROUND OF THE INVENTION The present invention relates to a multicomponent modular hydraulic system utilizing housing units for the various components which may readily be coupled to other similar units. The components may be in the form of directional valves, output controls, manifold and return lines, etc., so that by suitably connecting units having the necessary components a wide variety of functions may be obtained with the system.

The principle object of the present invention is to provide a hydraulic system wherein the various components of the system are each individually contained in housing units which may readily be connected to other similar units bearing other components in such a manner that the coupling of the housings to one another also serves to operatively connect the components.

A further object is to provide such a system which is capable of withstanding relatively high pressures and wherein the units are readily interchangeable and replaceable.

In the foregoing and following description the term hydraulic" is meant to relate to all types of fluid systems including those systems utilizing water, air, oil, or other liquids or gases.

SUMMARY OF THE INVENTION The above and other beneficial objects and advantages are I obtained in accordance with the present invention by providing a hydraulic system comprising a plurality of components, which may be in the form of tank and return lines, directional valves, reducing valves, etc., each of the components being contained within a housing unit. The units are each generally rectangular in shape and formed of a plurality of opposed pairs of walls including end walls, front and rear walls, and top and bottom walls. At least one passageway extends into the interior of each unit in communication with the component contained therein and terminates on at least one of the walls. At least one of the opposed pairs of walls includes a first wall having surfaces adapted to engage in surface-to-surface contact, the second wall of the corresponding pair of another unit and a second wall adapted to similarly engage the first wall of the corresponding pair of another unit. Fastening means are provided for coupling the units to one another with the corresponding passageways terminating on abutting surfaces in aligned registry. The fastening means extend only partially through each of the units being coupled.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention is illustrated in the accompanying drawings wherein similar components bear the same reference numerals throughout the several views. Reference is first made briefly to FIG. 5 wherein a typical hydraulic control system 10 is schematically illustrated. The system 10 is adapted to drive the actuators or outputs 12 along a common manifold. These outputs may consist of motors, cylinders, rotary actuators, etc.

In accordance with the present. invention, such a system may easily be constructed by interconnecting a plurality of modular units, each such unit containing one of the elements called for in the schematic drawing. Thus, for example, in order to actuate motor 12a the various components contained within the subsystem l4 defined by the broken line border are required. This subsystem includes return and feed lines 16 and 18 which provide the actuating fluid to the subsystem from a pump 17 and supply reservoir 19 and returns the same; a reducing valve 20; a directional valve 22 and flow control valves 24. Together these components drive motor 12a in a desired manner. It should be realized that further along the manifold formed of the feed and return lines other subsystems formed of other components of various types are used to simultaneously drive and actuate their associated outputs.

Referring now briefly to FIG. 6, the circuit of FIG. 5 is shown formed of the modular units of the present invention. Thus, the feed and return lines, 18 and 16, are both contained in the manifold unit 28, the reducing valve 20 is contained in unit 30, the directional valve 22 is contained in unit 32 and the flowcontrol valves are contained in unit 34. The output motor 12a, (not shown in FIG. 6), is connected to cylinder ports in the manifold block through suitable tubing in a manner to be described forthwith.

The manifold unit 28 has both its ends mounted to other similar units each having its feed and return lines in aligned registry. The ends 36 and 38 of the manifold are sealed and connected to the fluid pump and reservoir not shown. The manifold units are mounted on a platform 40 and, as shown in FIGS. 3 and 4, shock mountings 42 such as rubber pads may be provided between the manifold units 18 and the platform 40 if desired.

Reference is now made to FIGS. 1 through 4 wherein the details of the modular hydraulic system units of the present invention are shown. In FIGS. 1 and 2, the details of a manifold unit 28 and a typical component unit such as the flow control valve unit 34 are illustrated. The manifold unit 28 is generally rectangular in shape and includes front and rear walls 44 and 46, end walls 48 and 50, and top and bottom walls 52 and 54. The bottom wall 54 includes two axially aligned threaded holes 56 to enable the unit to be bolted to base 40. Two

horizontal passageways or channels 58 and 60, extend completely through the manifold unit from end wall to end wall and terminate on each of the end walls. These passageways, when suitably connected, define the feed and return lines 18 and 16 of the system. It is to be noted that each of the terminals on end wall 50 are defined by a recessed channel 62 counterbored into the end wall and extending completely around the passageway terminals. The terminals on the other end wall, 48, are substantially flush with the end wall. The recesses 62 serve as seats for an O or other suitable gasket so that when the flush wall 48a of an identical manifold 28a is brought against the recessed wall an effective seal may be formed. Similarly, theflush wall 48 would serve to seal the recessed wall 50b, of an identical manifold 28b.

There are four vertical passageways, 64, 66, 68 and 70, extending partially through the manifold unit from the top surface 52. The vertical passageways terminate at openings on the surface which are substantially flush with the top surface. Two of the vertical passageways, 64 and 66, each communicate with one of the horizontal passageways 58 and 60 and are connected to the center of their respective passageways. The remaining passageways extend downwardly into the manifold unit and are connected to horizontal passageways which terminate in cylinder ports 65 and 67 on the unit rear. The motor 120 or other actuator is connected to ports 65 and 67.

In drilling the various passageways through the unit, it is sometimes necessary to drill a guide bore such as passageway 72, which terminates on wall 50 in recess 74. This passageway may be sealed with a conventional plug, which must be recessed below the surface of wall 50, or by means of an O ring inserted within recess 74, between wall 50 of the present unit and wall 48a of an adjacent unit. The latter method, however, does tend to produce additional forces tending to separate the adjacent units, and hence, is not suggested for high pressure systems.

As shown, recessed chambers 76 and 78 extend inwardly from the front and rear surfaces, respectively. Recess 76 is generally rectangular and is spaced inwardly of the top, bottom and end walls. Recesses 78 extend to the top and bottom walls, are spaced inwardly from the end walls, and are separated by a center divider 80. The front recess 76 provides a convenient compartment for receiving the electrical connections to be associated with the hydraulic system and in this connection openings 82 and 84 are provided in the end walls to permit passage of the electrical leads. Openings 82 and 84 are extended to front wall 44, thus enabling the electrical leads to be set into the unit without requiring snaking from unit to unit.

Recesses 76 and 78 also serve the important function of providing access to rear portions 86 and 88 of end walls 50 and 48, respectively. This permits several manifolds to be fastened to one another in end-to-end fashion without requiring that the fastener extend entirely through the unit.

It is undesirable to have the fastener extend entirely through the housing since this limits the pressure to which the manifold can be subjected since the maximum pressure is a function of the amount of elongation of the fasteners (leakage between adjacent units will occur when the fastener stretches enough to destroy the seal between the adjacent units), which in turn is a function of the initial length of the fastener. Thus, the manifold units 28 of the present invention are provided with four holes 90 drilled through end wall 48 into chambers 76 and 78 and four threaded holes 92 extending through end wall 50 into chambers 76 and 78. The holes 90 and 92 are in aligned registry so that threaded fasteners such as socket head bolt 94, may be positioned in chambers 76 and 78 and passed through openings 90 to engage the threaded openings 92b of another similar manifold 28b. Similarly fasteners can be positioned through openings 90a of an identical manifold 28a, to engage the threaded openings 92 thereby enabling the units to be connected. In this manner, the bolts 94 need only be sufficiently long to pass through the end wall openings 90 to engage the threaded openings of the manifolds to be joined. Four threaded holes 96 are also provided extending downwardly from top surface 52 and disposed about the vertical openings 64, 66, 68 and 70. A removable front plate 97 may be provided to protect the electrical connections in chamber 76, and in this regard aligned holes 99 and 101 are provided on the plate and unit to facilitate fastening. An opening 98 in plate 97 permits external electrical leads to be interconnected with the leads in the chamber as required.

A typical component unit 34, in accordance with the present invention, is also shown in FIGS. 1 and 2. Component unit 34 is also generally rectangular in shape and includes front and rear walls 98 and 100, end walls 102 and 104, and top and bottom walls 106 and 108. The component unit contains therein any hydraulic component, as, for example, the flow control valve, and the vertical passageways extending therethrough (to be described forthwith) bring the component in operative contact with the hydraulic fluid of the manifold and other associated components. Four passageways, 110, 112, 114 and 116 extend vertically through the unit in aligned registry with vertical passageways 64, 66, 68, and 70, respectively, of the manifold unit. Recessed channels 118 extend about the bottom terminals of the passageways while the top terminals are substantially flush with top surface 106. Recessed channels 118 serve to seat 0 rings or similar gaskets so that an effective seal may be drawn between the vertical passageways of unit 34 and those of the manifold unit 28 or between unit 34 and another similar unit such as 30. As shown in FIG. 3, a flow control valve such as 113 may be connected to the vertical passageways by suitable horizontal passageways for additional control. The flow control valve 113 is suitably bolted to the exterior of unit 113. It should be noted that valve 1 13 provides the function for which this particular block was designed to accomplish.

The four passageways 110, 112, 114 and 116 include tank and return passageways 110 and 112 and two intracomponent connecting passageways. If required, further passageways may also be provided to divert all or part of the hydraulic fluid flow for some additional function. These additional passageways could be connected to the tank, return, or intracomponent passageways and then terminate on the surface of the unit for receiving the additional function component (such as 113). Since it is essential to the present invention that the various vertical and horizontal passageways of the units be in aligned registry with similar passageways of other units, cross drilled holes 120 are utilized to divert the passageway around other passageways to develop the desired function. These holes are later plugged to ensure against leakage if they are not used to connect to some outside component as previously described.

As in the horizontal coupling of the manifold units and for the same reason, it is desirable to vertically couple the various units to one another with the shortest possible fasteners. To this end vertical holes 122 are provided disposed about passageways 110, 112, 114 and 116 and aligned with the threaded openings. Unique socket head cap screws are utilized to effect the vertical coupling. As shown in FIG. 1, each of the bolts 124 includes a threaded portion 126 extending downwardly from an enlarged cap 128. A socket 130 extends downwardly from the top surface 132 of the bolt and a threaded recess 134 is disposed below the socket. The threaded portion 126 is designed to engage the threaded recess of another similar bolt.

Referring now to FIG. 4, it is noted that each hole 122 is providedwith an enlarged top portion 136 designed to accommodate the cap 128 of bolt 124. In operation, a first unit, for example 34, is placed over the manifold unit 28 with its vertical passageways 110, 112, 114 and 116 aligned with passageways 64, 66, 68 and 70 and suitably sealed with 0 rings 138. Bolts 124 are then passed through openings 122 of unit 34 to engage the threaded holes 96 of unit 28. Another unit, for example 30, is then positioned above unit 34 with its passageways aligned with those of unit 30 and sealed with 0 rings. Bolts 124 are then passed through the openings 122 of unit 32 to engage the threaded portion of the heads of the bolts fastening unit 30 to the manifold. In a similar manner additional component units could be vertically added.

The method described above for coupling adjacent units has been found to operate satisfactorily under very high pressures which are sufficient for most uses. In the event that the system is to be operated in the ultra high pressure range, an alternate method of coupling adjacent units is disclosed in FIGS. 7 through 10. In accordance with this alternate coupling arrangement aligned channels 140 are drilled extending transverse to the units to be coupled as, for example, manifold units 28 and 28a. A short rod or pin 142, the diameter of which is substantially equal to that of channel 140 and the total length of which is equal to that of the combined depths of channels 140 and 140a is then inserted in both holes 140 and 140a. A hole 144 extends into each unit perpendicular to the pin receiving channel 140 and positioned proximal the end of channel 140. The portion of hole 144 above the pin channel is threaded to accommodate a making thread on the top portion of the associated screw 148. As noted in FIGS. 8 and 9, pin 142 is provided with a slot 146 which tapers inwardly from the top surface. The length of slot 146 is substantially equal to the combined distance of channels 140 and 140a measured to screw holes 144 and 144a. Socket head tapered shoulder screws 148 are used to secure the pin in position and in this connection it is to be noted that the portion 150 of hole 144 above the pin channel 140 is counterbored sufficiently to accommodate the head 152 of screw 148. As noted before, this portion of hole 144 is also threaded. The shoulder 154 of screw 148 is tapered at substantially the same angle as slot 146.

In operation, the units are secured to one another in accordance with this alternate procedure by passing pin 142 through channels 140 and 1400 of the units to be fastened with the top of tapered slot 142 aligned with the counterbored portion 150 of holes 144 and 144a and the bottom of the slot aligned with the bottom portion. Bolts 148 and 148a are then passed through the slot to engage threaded portion 150 and 150a respectively so that as the bolts are tightened the units are drawn toward one another.

Thus, in accordance with the above, a modular hydraulic system is provided wherein the various components are each contained in readily interconnected modules. The present invention thus facilitates the construction of a hydraulic system to perform any desired function and also permits, with relative ease, the replacement of any particular component to modify the system or to replace faulty or worn out parts.
