Definitions

  • a roller-type valve lifter is mounted in an internal combustion engine to reciprocate a push rod in response to rotation of an engine driven cam shaft.
  • a guide and anti-rotation device for the valve lifter comprises a vertica1ly-disposed leg which seats in a slot formed on the valve lifter and a pair of cylindrically shaped arms, extending horizontally from opposite edges of the leg, which seat in a circumferential groove also formed on the valve lifter.
  • a hook connected to an upper end of the leg by a reverse bend, seats in a bore formed in the cylinder block.
  • An object of this invention is to overcome the above, briefly described problems by providing an economical, non-complex and noise suppressing valve lifter guide.
  • the guide comprises a'vertically-disposed first guide portion seated in a first groove formed on the valve lifter and a pair of 'arcuately shaped second guide portions seated in a second groove formed circumferentially about the valve lifter.
  • a third guide portion is preferably connected to an upper end of the first guide portion by a reverse bend and is positioned in a bore formed in the engine block.
  • FIG. I is a sectional view of a pair of valve lifters and attendant guides, operatively mounted in an internal combustion engine
  • FIG. 2 is a top plan view of one of the valve lifters and guides.
  • FIG. 3 is an enlarged isometric view of the guide.
  • FIGS. 1 and 2 illustrate a portion of an internal combustion engine comprising a cylinder block having a plurality of cylindrical bores 11 formed therein to reciprocally mount valve lifters 12.
  • Each valve lifter has a roller 13 rotatably mounted on a lower, bifurcated end thereof by a shaft 14 secured in place by a retaining pin 15.
  • a cam shaft 16 is rotatably mounted in the engine tohave a cam lobe 17 thereof engage each roller to reciprocate the valve lifter and an engaged push rod 18 in a conventional manner.
  • a spool-like body portion 19 of the valve lifter has a lower annulus 20 and an upper annulus 21 defined therein.
  • the lower annulus communicates lubricating oil from a passage 22, formed in the cylinder block, to
  • An upper land comprises a single, vertically disposed first guide portion or leg 26.
  • a pair of arcuately shaped second guide portions or arms 27 extend horizontally from opposite edges of a lower end of the attached leg and a third guide portion or hook 28 is connected to an upper end of the leg at a reverse bend 29.
  • the hook and arms are thus positioned onopposite sides of leg 26, as clearly illustrated in FIG. 3.
  • leg 26 When installed, leg 26 seats in groove 24 whereas arms 27 are disposed in annulus or second groove 21 to substantially circumvent body portion 19.
  • Hook 28 is disposed in a bore 30 formed on top of the engine block to prevent rotation of the guide. Reverse bend 29 thus projects upwardly above the block to fully expose it for easy removal for servicing purposes.
  • Spring-like arms 27 are preferably semi-cylindrical and have a diameter which is slightly larger than the diameter of bore 11, when in their relaxed, FIG. 3 condition, to effect a light press-fit relationship with the bore when installed therein.
  • the ends of the arms are suitably spaced apart to adapt them for radial insertion into annulus 21 and about body portion 19.
  • a noise suppressing and damping action is provided during reciprocation of the valve lifter due to the presence of lubricating oil in annulus 21 and the close fit relationship existing between leg 26 and slot 24
  • the disposition of leg 26 in slot 24 and of leg 28 in bore 30 will function to retain the guide in position during all phases of engine operation and will'prevent rotation of the valve lifter relative to the engine block.
  • valve lifter reciprocally mounted in a bore formed in said support member and having a first vertically disposed groove and a second circumferentially disposed groove formed thereon,
  • a one-piece valve lifter guide comprising a vertically disposed first guide portion disposed in said first groove and a pair of arcuately shaped second guide portions extending horizontally from opposite edges of said first guide portion and disposed in said second groove, and
  • anti-rotation means for preventing rotation of said valve lifter relative to said stationary supportmember.
  • said anti-rotation means further comprises a third guide portion, connected-to an upper end of said first guide portion, seated in a bore formed in said stationary support member.
  • valve lifter has a roller rotatably mounted on a lower end thereof and further comprising a cam shaft rotatably mounted in said stationary support member, said cam shaft having a cam lobe engaging said roller to reciprocate said valve lifter upon rotation of said cam shaft.
  • first guide portion constitutes a single leg and said second guide portions constitute a pair of semicylindrical arms having their ends spaced apart to adapt them for radial insertion about said valve lifter.
  • tion constitutes a hook connected to the upper end of said first guide portion at a reverse bend to position said second guide portions and said hook on opposite sides of said first guide portion.
