Definitions

  • the application relates to a piston pump for conveying liquids.
  • the technical problem underlying the invention therefore consists in the creation of a piston pump which can be produced cost-effectively, which is constructed in a space-saving manner and is not susceptible to faults, and permits an exact metering of the conveyed medium.
  • a pump housing provided with a suction nozzle and a pressure nozzle and having a cavity, in the cavity of which a essentially circular disk is rotatably mounted and the disk is provided with a diagonally running cylinder bore in which a piston which can be driven by a crank mechanism is arranged.
  • Another solution according to the invention has a pump housing which is provided with a suction nozzle and a pressure nozzle and has a cavity, in the cavity of which a cylinder is pivotably mounted about bearing journals arranged at one end and with integrally molded elastic ends on its end facing the suction or pressure nozzle Provide cloth and a piston driven by a crank mechanism is arranged in the cylinder.
  • Piston pumps of this type can be constructed in a space-saving manner and manufactured at low cost. They have no obstructive valves, which can hinder the malfunctioning of the pumped medium, for example. These piston pumps can be realized with low flow losses due to correspondingly large and streamlined cylinder bores, which also allow an exact measurement of the delivery volume.
  • the piston pump has a pump housing 1 with a suction port 2 and a pressure port 3.
  • An essentially circular disk 5 is arranged in an approximately circular, upper part of the cavity 4. This disk 5 is rotatably supported about an axis (imaginary) extending through its center 6.
  • the disc 5 has a diagonally running cylinder bore 7, in which the piston 8, which can be driven by the crank mechanism 9, is arranged.
  • crank mechanism 9 If the crank mechanism 9 is rotated again by a quarter turn, the operating position 1d is obtained: the piston 8 has moved upwards out of the lower dead center position and thereby pivoted the disk 5 to the right by approximately 25 degrees. As a result, the end of the cylinder bore 7 has reached the area of the pressure port 3 through which the liquid is now conveyed out.
  • FIGS. 1 and 2 Components that are identical in FIGS. 1 and 2 are provided with the same reference symbols.
  • the pump housing 1 is closed with the cover 12 and the crank mechanism 9 is connected to the pump shaft 13.
  • the embodiment of the piston pump shown in FIG. 3 essentially corresponds to the embodiment according to FIGS. 1 and 2.
  • the pump housing is expanded by a further cavity 14 which is sealed off from the cavity 4 and in which one of several Spur gears 15, 16 existing reduction gear arranged and which is also closed with a cover 17.
  • the drive shaft 18 provided with teeth at the inner end is passed through the cover 17 and is mounted in it.
  • FIGS. 4 and 5 the components which are identical to other exemplary embodiments are provided with the same reference symbols. These exemplary embodiments differ from the previous ones by the drive of the piston 8.
  • a circular disk 20 is attached eccentrically to the pump shaft 19. This disc 20 is surrounded by the ring 21, on the circumference of which the piston 8 is attached.
  • the pump shaft 19 is supported both in the pump housing 1 and in the cover 12.
  • the pump shaft 19 is driven by a worm gear consisting of worm wheel 22 and worm 23.
  • the embodiment of the piston pump according to FIGS. 6 and 7 differs from the embodiment of FIGS. 4 and 5 in the following way: the previous disk 5 has been replaced by the cylinder 24, which is provided with the journal 29 at the lower end. With these journals 29, the cylinder 24 is pivotally mounted in the pump housing 1 and the cover 12. At the upper end, the cylinder 24 is provided with integrally molded elastic tabs 26, which ensure a good seal between the cylinder interior and the suction port 2 or pressure port 3.
