Definitions

  • the present invention relates to a counterpiston machine, especially counterpiston motor.
  • a counterpiston machine in which a counterpiston by means of a piston rod and a transverse yoke is connected to two pull rods the ends of which are provided with displacement pistons. These pistons are guided by cylinders located parallel to the motor cylinders. The liquid columns in the annular chambers of these displacement piston cylinder systems extend into a common chamber in which they act upon the annular surface of a piston which latter is, by an additional piston rod, connected to another counterpiston.
  • the last-mentioned piston together with a cylinder relative to which said last-mentioned piston is movable forms a stroke displacing device by means of which a hydraulic linkage system is connected to a rotary displacer.
  • the pressure fluid delivered by said displacer is divided in at least two branch flows.
  • the invention is based on a counterpiston machine, preferably a counterpiston motor, in which at least two displacement pistons are by pull rods and a transverse yoke connected to one of the counterpistons, and in which the liquid columns acted upon by the said pistons lead to a chamber in which said liquid columns act upon the annular surface of a piston which is connected to the other counterpiston by a piston rod.
  • the invention is seen primarily in that this piston is formed by a crosshead of a connecting rod-crank driving mechanism or connected thereto.
  • the motor cylinder 1 provided with upper and lower inlet and outlet openings 2 has reciprocably mounted therein two counterpistons, namely, the upper piston 3 and the'lower piston 4.
  • the piston rod 5 having one end connected to the lower piston 4 has its other end connected to a crosshead 6 which in conformity with the present invention forms a piston and is reciprocable in a vertical cylinder 7.
  • the connecting rod 8 pivotally connected to the crosshead 6 is linked to a crank throw of the crankshaft 9.
  • the piston rod 10 which has one end connected to the upper piston 3 and extends upwardly out of the motor cylinder 1 has its other end connected to a transverse yoke 11. From said yoke, two pull rods 12 extend downwardly parallel to the motor cylinder 1.
  • the lower ends of said rods 12 have connected thereto displacement pistons 13 which are reciprocable in vertical cylinders 14.
  • Those chambers of the cylinders 14 which are located above the pistons 13 communicate with the chamber located above the crosshead 6 and pertaining to the cylinder7.
  • the total thus formed chamber is filled completely with a liquid, for instance, oil which is approximately noncompressible.
  • the diameter of the cylinders 7 and 14 are so selected with regard to each other that the volume displaced by the crosshead 6 when the latter moves, for instance, upwardly to a certain extent equals the sum of the volumina by which the chamber above the pistons 13 increases when these pistons move downwardly to the same extent.
  • the cylinders 14 are at the bottom thereof closed by a cover 15, and in the thus formed chambers below the pistons 13 there is enclosed a gas which preferably is under an overpressure.
  • crankshaft 9 rotates in the direction of the arrow A so that the crosshead 6 andthe lower piston 4 move upwardly.
  • the crosshead 6 displaces oil from cylinder 7 into the cylinders 14.
  • the pistons 13 and thus the upper piston 3 move downwardly by the same distance by which the crosshead 6 and the lower piston 4 move upwardly.
  • the gas in cylinders 14 below the displacement pistons 13 will act as buffer and will thus assure that when starting the motor, the pistons 13 will engage-the liquid columns in'the cylinders 14.
  • the quantity of liquid in the total chamber above the pistons 6 and 13 may by tapping be reduced or may be increased by introducing an additional quantity of fluid. To this end, it is possible in a simple manner, even during the operation of the motor, to change the dead center position of the upper piston 3 whereby the compression ratio can be varied.
  • the design according to the invention furthermore makes it possible to hydraulically relieve the loaded sliding surfaces of the connecting rod-crank driving mechanism.
  • the pressure field 16 at the upper portion of the crosshead journal is, through a bore 17 in the crosshead, in communication with the chamber above said crosshead-in which the liquid hasthe respective pressure required for power transmission. This pressure thus relieves the sliding surface of the pressure field 16.
  • gas below the displacement pistons 13 may be of any suitable type, air has proved very satisfactory in this connection.
  • a counterpiston machine especially counterpiston motor, which includes: first cylinder means having inlet means for' a fuel gas mixture and also having outlet means for the exhaust gases, counter running first and second piston means reciprocable in said first cylinder means and operable to compress a fuel gas mixture therebetween prior to the ignition thereof and to exhaust the combustion gases from therebetween after effected ignition, hydraulic chamber means adapted to be filled with hydraulic fluid and comprising second cylinder means and third'cylinder means, crosshead piston means reciprocably guided by said second cylinder means and reciprocably connected to said first counter piston means, one side of said crosshead piston means forming a movable wall portion of said hydraulic chamber means, at least two displacement pistons reciprocable in said third cylinder means and forming movable wall portions of said hydraulic chamber means, the total displacement of said From the pressure field l6, bores l8, 19 lead into the movable wall portions formed by said displacement pistons substantially equaling the displacement of said movable wall portion formed by said crosshead piston means, yoke means connected to said second piston means, and pull
  • said third cylinder means comprise elastic buffer means located at that side of said displacement pistons which face away from said hydraulic chamber means.
  • a machine according to claim 1 which includes means for varying the filling of said hydraulic chamber means to thereby vary the dead center position of said first counter running piston means.
  • crank drive means comprising connecting rod means pivotally connected to said crosshead piston means, said crank drive means including conduit means establishing communication between load receiving areas of said crank drive means and the interior of said hydraulic chamber means.
