Definitions

  • This invention relates to a vacuum operated engine for ⁇ driving pumps and other mechanisms.
  • a further object is to provide means whereby the shifting of the valves from one extreme position to the other is eected abruptly.
  • a further object is to combine with the engine a vacuum ump utilizing high and low pressure cylin ers whereby its efclency is increased to the maximum.
  • FIG. 1 is a plan view of the vacuum engine, the cover eing removed and apump being combined therewith.
  • Figure 2 is a longitudinal section through the engine, the cover thereon and the pump.
  • Figure 3 is a section on line 3 3, Figure 2.
  • Figure 4 is a section on line 4 4, Figure 2.
  • Figure 5 is a ction on line 5 5," Figure 2.
  • Figure 7 is a pers ctve view of one of the double valves an itsymounting.
  • a master piston 2 secured to an intermediate portionI of a rod 3 adapted to reciprocate wlthin openings 4 inthe heads 5 of the cylinder.
  • pump pistons 6 and 7 To the free ends of the rod are connected pump pistons 6 and 7 respectively, the piston 6 'being designed to work within a low pressure cylinder 8 extending beyond one of the heads 5 while the small piston 7 is adapted to reciprocate within a high pressurecylinder 9 extending from the other head.
  • the inner end of each of these ylinders is open.
  • Theouter end of cylin- Ver 8 is provided with ahead 10 in which estanca 'os are located an outlet port 11 and an inlet port 12.
  • a ball valve 13 is normally seated by gravity in the port '12 so as to o en automatically when air is drawn into t e cylinder 8 but to close when the air in the cylinder is placed under compression.
  • Another ball valve 14 is seated by gravity in the port 11 so as to open during the compression stroke of the piston 6 and close duringthe suction stroke.
  • Port 12 opens into the external atmosphere when its valve 13 lis unseated while port A ⁇ 11 opens into a pipe 15 which extends to the inlet port 16 in the head 17 at the outer end of the cylinder 9.
  • a ball valve 18 is seated by gravity in the port 16 so as to close during the compression stroke of piston 7 and open during the suction stroke thereof.
  • An outlet port 19 is formed in the head 17 and has a ball valve 20 normally seated by gravity therein so as to close during the suction stroke of piston 7 and open during the compression stroke thereof.
  • This port 19 communicates with a fiexible tube 21 used for conducting air to the vehicle tire or other structure in which air is to be compressed,
  • the master piston 2 is to be .operated by vacuum.
  • a port 22 is formed in one head ofthe c linder ⁇ 1 Vand another port 23 1s Acorrespon ly located inthe other head of said cylinder.
  • the two ports are connected by a pipe 24 in communication with a pipe 25 adapted to be connected to. a tank or other structure containing a partlal vacuum.
  • Pivotally mounted on the inner side of each head 5 is a forked lever 26 which straddles the rod 3 and carries a valve for controlling the adjacent port.
  • One of these valves has been shown at 27 while the other has been indicated at 28.
  • An arm 29 1s extended from each of the levers 26 and works freely through an inlet port 30 or 31 formed in the respective heads 5.
  • One of these arms has a valve is provided with a valve 33, the. two valves bein located outside of the cylinder. Extending from each of the valves 32 and 33 is a linger 34 and pivotally connected to these fingers is a connecting rod 35. This rod slides within a lug 36 extending from the cylinder 1 and provided with a knife edge 37. A leaf spring 38 is secured to and moves with the rod 35 and extends over the knife edge, this being provided with a downwardly exten ed V-shaped portion 39. The parts are so proportionedthat when this V-shaped portion is located at thel right of the lug 36 the valves 32 and 28 will be held on'their seats while the valves 27 and 33 ⁇ willbe unseated. When the V- shaped portion 39 is positioned at the other side of the knife edge, the sitlons of the valves will be reversed, va ves 33 and 27 being seated while valves 32 and 28 -are unvseated. y
  • each of the levers 26 Secured to each of the levers 26 is a leaf secured to each lever and in path of the free end of theleaf spring thereon is a coiled spring 41, the two springs j 40 and 41 being normally spaced apart.
  • spring ating with the knife edge 37 constitutes an eilicient means for preventing the valves .from fluttering. Consequently they will be held firmly to their seats until unseated by the master piston in the manner e lained.
  • vacuum as herein is not intended to-mean a complete vacuum, but applies to any area ratified by the suction or withdrawal of air therefrom.
  • a vacuum operated engine including a ymajor supported valves for successively closing the ports in each head, a connection between all ofthe valves to insure simultaneous movement thereof, cooperating iixed and yielding means for holdlng all of the valves in either of their extreme positions, a piston within the cylinder and resilient means for transmitting motion therefrom to the valves.
