Definitions

  • the displacement pump is therefore designed and dimensioned according to the most extreme conditions.
  • the adaptation must be carried out with a blow-off valve as a countermeasure.
  • a blow-off valve as a countermeasure.
  • the unnecessarily expended energy is then not only used unused due to the necessary blowing off, but is also directly misused by heating the recirculating oil.
  • blowing off the oil via a pressure relief valve leads to foam formation, which significantly affects the lubricating properties.
  • the outside diameter of the disc 4, which cannot be seen in this section, is shown in dashed lines.
  • the spiral 5a lies both at its entry-side end and at its exit-side end with its inside against the inner peripheral wall 8 of the delivery chamber 6. On the one hand, it thus encloses the crescent-shaped work space 12 with its inside. On the other hand, the spiral is open on its outside against both inlet 2 and outlet 3, i.e. at the same time, it sucks in and discharges there, as indicated by the corresponding arrows.
  • the spiral 5b is in the second end position. It encloses the working space 12 with its outside and is opened with its inside against the inlet 2 and the outlet 3.
  • the spring means 13 used here are a number of helical springs arranged uniformly over the circumference. At one end, these springs are supported by ball joints 28 in corresponding pans on the inner wall of the housing half 7 '. With their other end, they also act directly on the rear side of the disc 4, which is not provided with displacement bodies, via ball joints, which is also equipped with ball sockets on the corresponding diameter for this purpose.
