Definitions

  • This invention is useful in any fluid metering valve structure; however, it is particularly adapted for use in an internal combustion engine for metering lubricating oil to a conventional rocker arm which connects a valve to a push rod.
  • the cylinder valves in spring biased abutting relation with one side of the rocker arm are caused to open and close by a reciprocating hollow push rod which is in abutting relation with the other extremity of the rocker arm.
  • the push rod engages a valve lifter such as a hydraulic tappet.
  • the valve lifter is caused to reciprocate by a rotating cam journaled in the crank case.
  • the reciprocating valve lifter is supplied lubricating oil under pressure from a source of lubricant through the hydraulic tappet into the hollow push rod and up to the rocker arm.
  • FIG. 6a is a perspective view of still another valve plate used in the embodiment of the invention seen in FIG. 2.
  • FIG.1 of the annexed drawings there is shown a rotating cam 5 journaled for rotation in a crank case 6.
  • a valve lifter in the form of a hydraulic tappet 7 is slidably disposed in a bore 8 in the crank case 6.
  • the tappet 7 reciprocatingly coacts with the rotating cam 5.
  • a hollow push rod 9 engages the other extremity of tappet 7 and extends through a bore 10 in the cylinder head 11 where it pivotally abuts one free extremity of a rocker arm 12.
  • the rocker arm 12 rotates about a spherical fulcrum means generally indicated at 13, which is threadedly secured to the cylinder head 11.
  • a valve 14 communicating with a cylinder 15 pivotally abuts the other extremity of the rocker arm 12.
  • FIG. 2 there is shown in cross section a hydraulic tappet 7, improved in accordance with this invention and shows a substantially cylindrical hollow plunger 17, which is centrally disposed within the hydraulic tappet 7.
  • the plunger 17 and the hydraulic tappet 7 move relative to each other along a common axis
  • the cylindrical wall 18 of the plunger 17 defines a lubricating oil or fluid reservoir 19.
  • the upper extremity 30 of the plunger 17 is open, being adapted to rotatably support a flanged closure member, push rod seat member or valve seat 31.
  • the push rod seat member 31 has a flange 32 which supportingly coacts With the annular extremity 30 of the plunger 17.
  • the push rod seat member 31 at its upper extremity is provided with a socket 47 adapted to engage and support the push rod 9.
  • Located in the push rod seat member 31 and extending therethrough is a passageway 33 which communicates with the hollow push rod 9 and the reservoir 19 In the preferred embodiment of the invention, the passageway 33 is centrally disposed in the push rod .seat member 31.
  • the other extremity or surface 34 of the push rod seat member 31 extends into and closes the reservoir 19.
  • the surface 34 is a surface of revolution generated about the longitudinal axis of the passageway 33.
  • the portion of surface 34 adjacent the axis extends further into the reservoir than the portion of surface 34 remote from the axis and adjacent the periphery of the push rod seat member 31.
  • the surface 34 of the push rod seat member 31 is a conical surface of revolution generated about the longitudinal axis of the passageway 33 and has its projected apex extending into the reservoir 19.
  • the conical angle of the surface 34 as seen in FIGS. 2, 3, 4 and is greatly exaggerated for illustrative purposes.
  • the conical angle 27 of the surface 34 is approximately 1 to a plane perpendicular to the axis centerline of the push rod seat member 31 as seen in FIG.
  • the included cone angle is approximately 178 when used in combination with a passageway having a diameter of .086 inch. Further restriction under conditions of high pressure drop may require that the cone angle be as low as A or conversely as high as 5 where the pressure drop is low or more flow is required. Alternately, for a fixed cone angle, a change in the desired flow range may be obtained with a variation of the hole diameter.
  • Resilient means generally indicated at 36, and disposed in the reservoir 19, has its free extremity 37 resiliently engaging the valve plate 35 in radially offset relation to the axis of the passageway 33 in the push rod seat member 31.
  • the valve plate 35 is thereby maintained in predetermined tilted relation to and adjacent the passageway 33 against the adjacent surface 34 of the push rod seat member 31.
  • the valve plate 3 5 partially obstructs the passageway 33 and serves to meter a continuous flow of fluid or oil therethrough.
  • the other extremity of resilient means 36 is adapted to abut the plunger 17 In the embodiment of the invention shown in FIG.
  • the resilient means 36 is a coil spring having its upper extremity 37 resiliently and eccentrically coacting against the valve plate 35 so as to maintain the valve plate 35 in tilted relation to the passageway 33.
  • the lower extremity 38 of the spring 36 abuts the lower extremity of reservoir 19.
  • the resilient means 36 is a hollow cylinder or sleeve 43 supported within the reservoir 19.
  • a resilient diametrically projecting finger 44 is secured to one extremity 45 of the sleeve 43 and disposed at an obtuse angle with respect to the side wall of sleeve 43.
  • the free extremity of the resilient finger 44 is adapted to hold the valve plate 35 in tilted relation to the passageway 33 of the push rod seat member 31 to meter a continuous flow of fluid or oil therethrough.
  • the resilient means 36 is included in the embodiment of the valve plate 35 shown in FIG. 6.
  • a pair of resilient finger portions 51 and 51a are struck from the planar disc portion 52.
  • the disc portion 52 is adapted to coact as a valve plate against the surface 34 in tilted relation to and adjacent the passageway 33 of the push rod seat member 31 to meter a continuous flow of fluid or oil therethrough.
  • the finger portions 51 and 51a are supported on a ledge or in a circumferential groove in the walls of the reservoir 19 and, hold the disc portion 52 in metering relation to the aperture 33.
  • FIG. 6a Another embodiment of the combined valve plate 35 and the resilient means 36 is shown in FIG. 6a.
  • An annular rim 52a is struck from the planar disc 51a.
  • the rim 52a similarly rests on a ledge or in a circumferential groove in the reservoir 19 holding the disc 51a in metering relation to the aperture 33.
  • valve plate 35 tends to rotate within the bore or chamber 19 relative to the conical face 34 by reason of the fact that the push rod seat member is resisted from rotating with the valve plate, through the frictional engagement of socket 47 thereof with push rod 9.
  • the valve plate 35 contacts the conical surface 34 along a line or at least two points where the surface 34 is purposely interrupted by grooves placed in the surface 34 concentric with the passageway 33. Because of this contact along the conical surface 34 and the effect of the relative rotation of the normally contacting parts, there is a wiping action between the valve plate 35 and the surface 34 which maintains the interface free of foreign matter. In devices where only one point contact is established between the valve plate and the push rod seat member, the cleaning action is absent or far less noticeable, and clogging frequently results. When the valve plate and the surface of revolution against which it 'bears are so interrelated that this aforementioned contact between the two is established, the normally occurring relative rotation between these parts effects a cleaning action on the valve plate 35.
  • a valve lifter including a hollow plunger having an open end and defining a fluid reservoir, a closure member fitted on the open end having a centrally disposed passageway extending therethrough communicating with the reservoir, and a fluid inlet extending through the wall of the plunger, the improvement which comprises:
  • a closure member (a) a closure member, the inwardly facing surface of which is a surface of revolution generated about the longitudinal axis of the passageway, the portion of the surface adjacent the axis of generation extending farther into the reservoir than the portion of the surface remote from the axis and adjacent the periphery thereof;
  • valve plate disposed in the hollow plunger adjacent said surface in tilted partially obstructing relation to the passageway for metering and filtering the flow of fluid therethrough;
  • valve plate is a planar disc having a diameter larger than the diameter of the passageway and smaller than the diameter of the reservoir.
  • a flow metering assembly for metering fluid under pressure through a passageway in a valve seat comprising:
  • valve plate larger in diameter than the passageway disposed adjacent and in tilted relation to the passageway, and partially obstructing the passageway for metering and filtering fluid therethrough;
  • a fluid metering assembly comprising:
  • a closure member supported on the open end of the reservoir, having a centrally disposed passageway extending therethrough communicating with the reservoir, a surface of the member adjacent the reservoir being a surface of revolution generated about the longitudinal axis of the passageway, the portion of the surface adjacent the axis of generation extending farther into the reservoir than the portion of the surface remote from the axis and adjacent the periphery thereof;
  • valve plate disposed in the reservoir adjacent to and in tilted partially obstructing relation to the passageway for metering and filtering the flow of fluid therethrough;
  • biasing means disposed in the reservoir supporting the planar disc with its finger portion.
  • valve plate is a planar disc having a diameter larger than the diameter of the passageway and smaller than the dimeter of the reservoir.
  • a fluid metering assembly having a valve seat with ing towards the other adjacent surface.
