Definitions

  • the purpose of the invention is to simplify the circuits, which should be flexible for different cooling requirements (aircraft or truck, unit or ship engine), as well as the use of a heat-insulating motor technology for cooling and lubricating axial motors.
  • the solution to the problem is that the same medium is used for cooling and lubrication, and in the arrangement of a central distributor groove, in which the various cooling and lubricating circuit combinations can be freely selected by simply repositioning cross-section locks, without component variants .
  • FIG. 1 shows one half of an axial motor which converts the oscillating movement of the pistons (13) in the cylinders (14), which are arranged axially around a wobble shaft (15), into a rotation of the wobble shaft.
  • the cylinders are covered by heads (16) and these in turn by a control housing (17), which is connected to the motor housing (34) at the same time via the bearing bracket (18).
  • the control housing on each engine side has two oil pumps (1) and (2) which are driven by the crankshaft (15). By the method described in FIG. 2, the oil either reaches the crankshaft in the direction of the arrow (via space (19)) and forms a lubricating and spray oil circuit, or it reaches ring space (20) and forms the cooling circuit.
  • Cooling circuit The oil flows from the annular space (20) into the annular spaces (21) of the individual cylinders. These annular spaces (21) serve to wash around the cylinder area, which is constantly covered by the piston crown from the spray oil (22). The oil reaches an annular collecting groove (23) in the head (16). from which it flows through a bore (24) into the control housing (17), from where it gets back into the oil container (25). The annular spaces (20) on both sides are connected by pipes (26).
  • Lubrication and spray oil circuit The oil can flow from one side of the annular space (19) to the other side through the swash shaft (15) and ensures lubrication of the base bearings.
  • Fig. 2 shows a section of the annulus
  • the bores leading to the outside or coming from the outside are: lines from pump (1) and (2) and lines (3), (4) and (11) for connections to external devices such as filters, coolers, thermostats and manometer.
  • the bores (10) lead the oil into the interior of the swash shaft (15) via space (19), and the bore (9) connects the annular space (32) to the annular space (20) on the rear of the bearing bracket ( 18).
  • the bores (38) each lead to overpressure valves.
  • the ring space is divided into ring sections by five removable locking blocks ( 5 ) , ( 6 ) , (7), (8) and (12).
  • the following arrangements are possible (blocks (5) and (8) always remain in the position shown): Arrangement 1: Pump (1) and (2) as lubricating oil pumps (with filtering and cooling). (6) is removed (connection (11) tight): oil flows via (3) to the filter and cooler to (4) and through holes (10) in the wobble shaft. Bore (9) is blocked by blocks (12) and (8) (if only one pump is used,
  • Arrangement 4 pump (1) as a lubricating oil pump with filtering and cooling, pump (2) as a cooling oil pump without filtering and cooling:
  • Arrangement 5 Pump (1) as a lubricating oil pump with filtering and cooling, pump (2) as a cooling oil pump with cooling: (7) is removed: Oil flows as cooling oil via (11) and cooler after connection (11) on the other side and bore ( 9) the other side. Oil flows as lubricating oil like arrangement 4. Combinations of these arrangements on both engine sides are, for example, a combination of arrangement 1 with 2 or 3. It is advantageous for the manufacture of the components that 100% tightness of the respective sections and circuits is not necessary with respect to one another, since it is the same Medium acts.
  • FIG. 3 shows a pendulum ring (28) via which the oil from the rotating wobble shaft (15) and the rotating support sleeve (33) find a way into which the connecting rod (29) executes a pendulum movement.
  • This pendulum ring (28) has a circumferential collecting groove on its inside, from which the oil reaches the connecting rod oil bore (36) via branch bores (35).
  • the chamfering of the bore (35) on the contact surface of the pendulum ring / connecting rod is so large that oil continues to flow even at the maximum stroke.
  • the ring (28) is secured against rotation by the pins (37), which, however, leave it enough play to compensate for the pendulum movement.
  • Fig. 4 shows a cross section through an annular space barrier (section CC): A cylindrical rotary part (12) or a cylindrical sleeve is inserted into a hole that is larger and deeper than the annular space cross section. A plate spring ( 39 ) ensures that the front end seals.

Abstract

Un moteur à combustion interne possède des cylindres agencés axialement autour d'un arbre oscillant. On utilise pour le refroidissement et la lubrification le même milieu fluide qui peut être acheminé, depuis l'intérieur de l'arbre oscillant, aux endroits à lubrifier et à refroidir, ainsi que depuis l'extérieur, aux cylindres et culbuteurs.
