Definitions

  • the present invention relates to a vibration generator with working pistons displaceably guided in displacement working chambers and with a pressurized fluid as the working medium according to the preamble of the independent claim.
  • CH-A 524 771 describes a method and a device for adjusting a working piston in a cylinder.
  • the working piston is vibrated by supplying and removing a pressure medium, for which purpose a control unit is present between the working cylinder and a storage device for the pressure medium.
  • this control unit there is a control cylinder with a control piston provided with axial grooves.
  • the control piston is both axially displaceable and rotatably driven in order to direct a controlled amount of the pressure medium in the desired direction.
  • Such an arrangement requires three lines for the pressure medium between the accumulator and the working cylinder in a one-sided preloaded piston and four lines in a double-acting cylinder, which have to be sealed accordingly and, in addition to a loss of power, result in a delay in the effect on the working cylinder, so that the Vibration frequency can only be increased up to an order of magnitude of 100 Hz.
  • the invention is intended to create a perfectly functioning vibration generator which has no expensive processing points and with which mechanical vibrations of up to several 1000 Hz can be carried out.
  • a circular cylinder body 1 there are four cylinders 10, 20, 30, 40 arranged perpendicular to one another.
  • Each cylinder has a shoulder 17, 27, 37, 47 and in the cylinder part with the larger diameter there is a piston 13, 23, 33, 43, each with a piston rod 14, 24, 34, 44, which is sealed by a screwed-in sealing cover 78 are guided to the outside with a sealing washer 80 and a tension spring 82.
  • the piston 13, 23, 33, 43 divides the respective cylinder 10, 20, 30, 40 into an outer chamber 11, 21, 31, 41 and an inner chamber 12, 22, 32, 42.
  • the four inner chambers are together connected and filled with a hydraulic fluid.
  • Disks 50 and 60 with holes 51 and 61 lie on the outer surfaces.
  • the two disks 50 and 60 are rigidly connected to one another by means of a shaft 70 through the crossing point of the cylinder axes.
  • a housing 76 encloses the entire cylinder body 1 with the two disks 50 and 60, so that an upper pressure chamber 90 and a lower compensation chamber 92 are formed.
  • the pressure chamber 90 is connected via a connection 74 to a high-pressure store for fluid under pressure and the compensation chamber 92 is connected to a connection 72 to a low-pressure store.
  • the inner chambers 12, 22, 32, 42 are filled with liquid.
  • the disks 50 and 60 accordingly have two bores 51a, 51b and 61 a, 61 b. If the disks 50, 60 are rotated together, these bores lie over openings in the outer chambers of the cylinders of opposing cylinders. According to FIG. 3, the bores 51a, 51b lie over the openings 15, 45 and the bores 61a, 61 over the openings 26, 36.
  • Fluid under pressure thus flows according to the arrows A from the high pressure chamber 90 through the bores 51a, 51b and the openings 15, 45 into the outer chambers 11, 41 and the pistons 13, 43 are pressed into the position shown in FIG. 1. Because the bores 61a, 61b in the disk 60 and the openings 26, 36 are aligned with one another, the fluid can flow out of the outer chambers 21, 31 into the compensator drain chamber 92 so that the pistons 23, 33 can move under the pressure of the liquid in the inner chambers 12, 22, 32, 42 into the outer position, also shown in FIG. 1.
  • FIG. 4 shows another exemplary embodiment in which the pair of cylinders 100 is designed with a common axis and a circular jacket cross section.
  • the cylinder pair 100 is enclosed by a control cylinder 101, which is connected to a drive indicated by the arrow C.
  • the pair of cylinders 100 has openings 102, 103. These openings 102, 103 are elongated in the direction of the surface lines and their longitudinal axes lie in a common plane through the cylinder axis and on opposite cylinder sides.
  • the control cylinder 101 is provided with four holes 104, 105, 106, 107, the axes of which are likewise arranged in a common plane through the axis of the control cylinder 101. These holes are arranged in pairs offset from one another in such a way that they are alternately aligned with an outer part of the openings 102, 103 and with an inner part thereof.
  • the control cylinder 101 is encompassed by a likewise cylindrical housing 110.
  • the housing 110 has two annular webs 111, 112, so that three annular chambers 113, 114, 115 are formed between the control cylinder 101 and the housing 110.
  • the two outer annular chambers 113, 115 are connected by lines 116, 117, 118 to a fluid source for fluid under pressure and therefore represent the high-pressure chamber of the example described earlier.
  • the middle annular chamber 114 is connected via a drain 119 to the low-pressure side of the fluid source and therefore forms the compensation chamber according to the example described first.
  • the holes 104, 105, 106, 107 are now distributed such that the outer chamber 124 of the one cylinder divided by a piston 120 passes through the opening 102 and the hole 104 with the high-pressure chamber 113 and the outer chamber 125 of the other a piston 122 divided cylinder are connected to the compensation chamber 114 via the opening 103 and the hole 107.
  • the control cylinder 101 When the control cylinder 101 is rotated through 180 ° in the direction of arrow C, the high-pressure chamber 115 is connected to the outer chamber 125 via the hole 106 and the opening 103, and the compensation chamber 103 is connected to the outer chamber 124 via the hole 105 and the opening 102.
  • the two pistons 120, 122 and the piston rods 121, 123 therefore perform an opposite movement, directed to the left in the drawing.
  • a rotational movement of the control means namely the control piston 101, results in a translatory movement of the piston rods, the stroke also being determined here by the amount of fluid flowing in and out and the frequency by the speed.
  • more holes can be provided in the disks 50, 60 according to FIGS. 1-3 or more holes in the control cylinder 101 in order to achieve a higher frequency at a lower speed.
  • the pistons 120, 122 in the exemplary embodiment according to FIG. 4 are sealingly connected to the cylinder wall with a soft membrane 131, 132. The stroke of the pistons 120, 122 is therefore limited by the dimensions of these membranes.
