Definitions

  • the invention relates to a reciprocating piston machine with a swivel disk which is adjustable in its inclination to the machine shaft and is driven by the machine shaft, in that it is connected in an articulated manner both to a sliding body guided axially on the machine shaft and at a distance from the machine shaft to a driver transmitting the driving force.
  • the pistons each have a joint arrangement on which the swivel plate is in sliding engagement.
  • a reciprocating piston machine of this type is known from DE-A-44 11 926 (JP-Note No. 081944).
  • the driver is in two parts, a first driver part fastened to the machine shaft being arranged at a considerable distance from the swivel disk and a second driver part engaging in the first articulated manner forming a lateral extension of the swivel disk.
  • the disadvantage of this design is that it significantly determines the minimum axial length of the machine.
  • the swivel disk having a thickened hub part has a relatively large moment of inertia due to its lateral extension, with a center of gravity far away from the axis of rotation, so that a sudden change in the rotational speed with corresponding inertia leads to an inclination adjustment of the swivel disk.
  • the invention has for its object to find a reciprocating piston machine of the type mentioned, which allows a particularly compact design with little effort for its manufacture, which opposes an adjustment movement of the swivel plate, low inertia and frictional forces and which prevents harmful spaces, exact compliance with internal dead center position of the reciprocating pistons guaranteed.
  • This object is achieved according to the invention in that the swivel disk has the shape of an annular disk and, at one point on its circumference, has an at least radially inwardly open engagement space into which the head of a driver firmly connected to the machine shaft engages.
  • Fig.l shows an axial section of an embodiment of the reciprocating piston machine, wherein the annular disc has its greatest inclination
  • FIG. 2 shows a representation corresponding to FIG. 1 with the smallest inclination of the ring disk.
  • FIG. 3 shows a separate illustration of the annular disk with its driver, corresponding to part of FIG. 2,
  • the reciprocating piston machine 1 has, for example, seven pistons 2, which are arranged next to one another in the circumferential direction of the machine and are guided in cylinder bores 3 of the machine housing.
  • the lifting movement of the pistons 2 takes place through the engagement of an annular disk 6, which extends obliquely to the machine shaft 5, into an engagement chamber 7, which is provided adjacent to the closed cavity 8 of the piston 2.
  • an annular disk 6, which extends obliquely to the machine shaft 5
  • an engagement chamber 7 which is provided adjacent to the closed cavity 8 of the piston 2.
  • the drive transmission from the machine shaft 5 to the ring disk 6 takes place by means of a driving pin 13 fastened in the machine shaft 5, the spherical head 15 of which engages, for example, in a radial bore 16 of the ring disk 6.
  • the position of the driver head 15 is selected such that its center 17 coincides with that of the ball of the ball segments 11, 12.
  • this center lies on a circular line that connects the geometric axes of the seven pistons to one another and also on a circular line that connects the center points of the spherical shape of the joint bodies 11, 12 of the pistons 2.
  • the head shape of the free driver end enables the inclination of the ring disk 6 to be changed by the driver head 15 forming a bearing body for the pivoting movement of the ring disk 6 which changes the stroke width of the pistons 2.
  • the shape of the engagement space 16 and / or the head 15 of the driver 13 can also be selected differently to achieve a different type of kinematics.
  • a further prerequisite for pivoting the ring disk 6 is the displaceability of its bearing axis 20 in the direction of the machine shaft 5.
  • the bearing axis 20 is formed by two bearing pins 22, 23 mounted on both sides of a sliding sleeve 21, which are also in radial bores 24, 25 of the ring disk 6 are stored.
  • the sliding sleeve 21 preferably has bearing sleeves 26, 27 on both sides, which bridge the annular space 28 between the sliding sleeve 21 and the annular disk 6 in a spoke-like manner.
  • the force for the angular adjustment of the annular disc 6 and thus for a control of the machine results from the sum of the pressures acting against each other on both sides of the pistons 2, so that this force is dependent on the pressure in the drive chamber 33.
  • a flow connection to an external compressed gas source can be provided to regulate this pressure. The higher the pressure on the drive chamber side of the pistons 2 or in the drive chamber 33 relative to the pressure on the opposite side of the pistons 2, the smaller the stroke length of the pistons 2 and thus the delivery rate of the machine.
  • the setting of the position of the sliding sleeve 21 and thus the stroke length of the pistons for regulating the delivery capacity of the machine can also be carried out by at least one spring 34, 35 which interacts with the sliding sleeve 21.
  • the sliding sleeve 21 is preferably enclosed between two helical springs 34, 35 which are arranged on the circumference of the machine shaft 5.
  • the position of the sliding sleeve 21, which is decisive for the delivery capacity, is also determined by inertial forces acting on the ring disk 6, in that the ring disk 6 rises with increasing rotational speed in the direction of the position according to FIG. 2, corresponding to a reduction in the stroke length of the pistons 2 and thus the delivery rate.
  • This mode of operation is significantly favored on the basis of the invention, since the mass of the annular disk 6 is arranged peripherally outwards in comparison to previously known swivel disks, by avoiding a massive design and avoiding a laterally formed driver.
  • Swivel plate 6 results from its limited to the ring shape

Abstract

L'invention concerne un moteur à pistons comportant un disque de verrouillage (6) annulaire, qui est entraîné par un arbre moteur (5) et dont l'inclinaison par rapport à ce dernier est réglable. Le disque entraîne des pistons (2) disposés adjacents en direction de la périphérie. Il est articulé avec un manchon coulissant (21) guidé axialement sur l'arbre moteur (5), ainsi qu'avec un entraîneur (13) transmettant la force d'entraînement et disposé à distance dudit arbre (5). La forme annulaire du disque de verrouillage (6) présente des avantages dynamiques et facilite sa production en série. Elle permet à l'entraîneur (13) de s'introduire d'une manière articulée dans un alésage radial (16) du disque (6) en prenant peu de place.
