Definitions

  • the invention relates generally to pressure fluid actuated vane motors and more particularly to reversible vane motors including a reversing valve, a motor cylinder, and a pair of outlet ports in the cylinder each having a cooperating valve means adapted to alternately close the one of the outlet ports offering during rotation in the respective rotational directions the first exhaust occasion from said cylinder. in such vane motors application of the valve means is directed towards gaining in both rotational directions of the motor the same maximum power output as attainable by a corresponding non-reversible motor.
  • a reversible pressure fluid actuated vane motor comprising a housing, a motor cylinder in said housing, a vane rotor rotatably mounted in said motor cylinder, a supply passage in said housing for supplying pressure fluid to said motor, inlet passage means in said housing connected to said motor cylinder, at twoposition reversing valve in said housing between said supply passage and said inlet passage means for derfining the rotational direction of said vane rotor in accordance with the position of said reversing valve, a pair of angularly spaced outlet port means in said motor cylinder, a cavity in said housing for receiving the exhaust from said outlet port means, a connection between said cavity and the 3,718,41 Patented Feb.
  • valve means in said cavity associated with each outlet port means for opening and closing said port means relative to said cavity, and closing means in said cavity engageable with said valve means for alternately closing the one of said valve means ofiering during rotation in the respective rotational directions the first exhaust connection between said cylinder and said cavity.
  • FIG. 1 shows a longitudinal section through a vane motor according to the invention seen substantially on the line 1-1 in FIG. 3.
  • FIG. 2 is a cross section on the line 2-2 in FIG. 1.
  • FIG. 3 is a cross section on the line 33 in FIG. 1.
  • FIG. 4 is a cross section corresponding to FIG. 3 through a modified embodiment of the invention.
  • FIG. 5 is a fragmentary view seen on the line 5-5 in FIG. 4.
  • the vane motor comprises a housing 10 which by screws, not shown, is clamped between a front cover 11 and a rear cover 12 and includes an inner cavity 16 with cylindrical end bores 13.
  • journalling bodies In the end bores 13 are inserted journalling bodies, a front body 14 and a rear body 15", carrying ball bearings 17 in which a vane rotor 18 is journalled by way of a rear journal 19 and a front drive shaft 20 concentrically with the end bores 13.
  • the vane rotor 18 is surrounded by a motor cylinder 21 fixed eccentrically with respect to the end bores 13 in the cavity 16 and having a pair of overhead inlet jackets 22, 23 connected thereto.
  • Vanes 25 which are radially movably guided within slits 24 in the rotor 18, slide in a well known manner against the inside of motor cylinder 21. Pressure fluid can pass from the respective inlet jacket 22, 23 into the cylinder 21 via inlet openings 26 and 27, respectively.
  • the motor cylinder 21 is provided with two angularly spaced alternative main outlet ports 28, 29 each including a number of bores or axial slots.
  • the cavity 16 around the intermediate portion of the cylinder 21 and around the inlet jackets 22, 23 thereof is in direct communication with the surrounding atmosphere via bores 31. In association with outlet bores there may if necessary be arranged some suitable conventional exhaust sound muflling device, not shown.
  • the cavity 16 has at the lower port-ion thereof a pair of pockets 32, 33 in which are received rubber bladders 34, 35 providing inflatable and deflatable expausible chamber devices. Between the pockets 32, 33 there projects upwardly a saddle shaped bead 44 into the cavity 16 providing a support for a two-position valve means 30 for alternate closing of the main outlet ports 28, 29.
  • the valve means 30 is designed as a rocker with rocker arms 36, 37, is journalled on the bead 44, and is preferably made of relatively rigid rubber material.
  • the rubber bladder 34 may be applied by way of expansion to act as a closing member for the outlet port 28, while against the other rociker arm 37 the rubber bladder 35 may be similarly applied by way of expansion for closing the outlet port 29.
  • Pressure fluid such as compressed air is supplied to the housing 10 via a hose 39 which is connected to a valve case 40.
  • a valve case 40 In the valve case 40 is arranged a two-position reversing valve 41, in the instant example designed as a flat slide adapted for manual actuation by means of a push rod 42 and adjustable to take two end positions.
  • the hose 39 In the end position illustrated in FIG. 3 the hose 39 is connected via the guide passage 38 of the reversing valve 41 to an inlet passage 43 formed partly in the housing 10 and partly in the rear journalling body 15. Via the journalling body 15 the inlet passage 43 is in communication with the interior of the jacket 22.
  • the reversing valve 41 by an inner recess 45 connects an inlet passage 46, likewise formed partly in the housing 10 and partly in the rear journalling body 15, with an axial passage 47 in the housing 10. Hhe axial passage 47 is connected to the cavity 16 and is thus via the bores 31 thereof in direct communication with the atmosphere. Via the journalling body 15 the inlet passage 46 is in communication with the interior of the inlet jacket 23.
  • the inlet passage 43 is through a passage 50 in the housing 10 in connection with the expansion chamber or interior of the rubber bladder 34 while the inlet passage 46 through a similar passage 51 is connected to the expansion chamber or interior of the rubber bladder 35.
  • the rubber bladder will be likewise relieved via the bore 51 and deflected or contracted and thus the rocking arm 37 is kept open and the outlet port 29 remains open with respect to the cavity 16 and the surrounding atmosphere for purposes of exhausting the working fluid with a minimum of throttling losses.
  • the first occasion for exhaust from the cylinder 21 would be offered by the outlet port 28 when passed by the vanes 25.
  • outlet port 28 since outlet port 28 is kept closed and inactive, the vanes will rotate on drivingly over an extended drive angle until actual exhaust takes place when the vanes 25 pass the active outlet port 29. The extended drive angle results in increased output of power.
  • valve 30 with the rocker arms 36, 37 is shown unaltered but is actuated by closing members provided by abutments settable against the rocker arms 36, 37.
  • abutments are formed as parts of eccentrics 52, 53 wherein the abutments are plane surfaces 54, 55.
  • the surfaces 54, 55 are alternately movable against the rocker arms 36, 37 and serve to arrest the eccentrics 52, 53 in two alternative adjusted positions and to cooperate lockingly with the rear surfaces of the rocker arms 36, 37.
  • the adjustment is had as a result of actuation of an axle 56 on which the eccentrics 62, 63 are fixed.
  • the axle 56 is turnably journalled in the housing 10 and can be adjusted to the desired angular position by means of a knob 57 outside of the housing 10.
  • a reversible pressure fluid actuated vane motor comprising a housing, a motor cylinder in said housing, a vane rotor rotatably mounted in said motor cylinder, a supply passage in said housing for supplying pressure fluid to said motor, inlet passage means in said housing connected to said motor cylinder, a two-position reversing valve in said housing between said supply passage and said inlet passage means for defining the rotational direction of said vane rotor in accordance with the position of said reversing valve, a pair of angularly spaced oulet port means in said motor cylinder, an exhaust cavity in said housing for receiving the exhaust from said outlet port means, a connection between said exhaust cavity and the surrounding atmosphere separate from said reversing valve so that substantially all of the exhaust fluid from said outlet port means is passed to the surrounding atmosphere without passing through said reversing valve means in said exhaust cavity associated with each outlet port means for selectively opening and closing said outlet port means relative to said exhaust cavity, and closing means in said exhaust cavity engageable with said valve means for selectively and
