Definitions

  • the invention relates to a diaphragm piston pump according to the Preamble of claim 1.
  • Such a diaphragm piston pump is from the DE-C2-39 03 049 known.
  • the membrane is here between the "covers" containing the delivery chambers clamped. This is supposed to be an inexpensive construction be created.
  • the invention is based on the object of a diaphragm piston pump of the type mentioned at the outset to create the is compact, allows modular construction, and is inexpensive to manufacture.
  • the lids are attached in several pump head elements divided up. It is basically a pump head element more required than pistons present in the engine are. These pumphead elements then become like this arranged laterally side by side that the second pump head element the lid and the delivery chamber for the first Pump head element, etc., depending on the number of pump head elements, forms.
  • the first pump head element arranged in series Pump head elements is then just a hydraulic housing, whereas the subsequent hydraulic housings and Cover with delivery chamber are.
  • the last one, i.e. the n + 1 pump head element is then only a cover with a delivery chamber.
  • the Membranes are between the pump head elements clamped. They are parallel to the longitudinal axis of the pistons aligned. The levels in which the membranes are clamped are, and the connection levels between each Form pump head elements, run parallel to the Longitudinal axis of the pistons.
  • the pump head elements are constructed similarly (only the first is just hydraulic housing and the last is only Cover), so that the most varied pump heads Have it assembled in the manner of a modular system.
  • the structure is very compact because all pump head elements on the Front of the engine to be installed.
  • the pump head elements can be used in different ways, for example connected by expansion screws become. But it is also possible to use other, non-positive Connections, for example with hydraulic or pneumatic provide force introduction.
  • the pressure and suction lines can be advantageously and the working valves in the pump head elements integrate. As a result, the compact design is still improved.
  • FIG. 1 Various embodiments are shown in the drawing, where the pump head is on the front an engine - in the illustrated embodiments with three pistons 1 - is attached.
  • the engine is not shown in detail.
  • the piston 1, which acts as a plunger are formed, dive in the embodiment of FIG. 1 directly into the pump head 5.
  • the working space 2 is filled in the usual way with a hydraulic medium.
  • the individual delivery chambers 4 are hydraulically connected in parallel. Each conveying chamber 4 is passed through by the working space a membrane 3 separated.
  • the pump head 5 is now in a number of pump head elements 5a, 5b, 5b and 5c divided. It is straightforward recognizable that the first pump head element 5a is only a Hydraulic element is. For this first pump head element 5a the second pump head element 5b forms the cover with the associated delivery chamber. Between the two pump head elements 5a and 5b, the membrane 3 is clamped. Corresponding This modular principle is based on the number of pistons continue to the last pump head element 5c, which is actually just a lid and just a feed chamber 4 contains, and with the last pump head element 5b clamps a membrane 3.
  • the pistons 1 are immersed not directly into the pump head, but it is a special guide housing 7 between the engine and pump head interposed. This is an extension to a Engine possible, the cylinder spacing with the Match the dimensions of the pump head elements.
  • Fig. 3 is a section along the line III-III of Fig. 2, wherein the pressure and suction lines 8.9 in the Pump head elements are integrated as well as the working valves 10. This is a particularly elegant solution. Of course it is also possible to use these lines and relocate the valves outside and with the help of appropriate To connect connecting flanges.
  • This homogenizer is a homogenizing valve in the form shown, formed from a stamp 11, the valve seat 12 and one Valve actuation 13. With valve actuation, a axial force is applied to the stamp, which is mechanical (e.g. with a compression spring), hydraulic or pneumatic can be generated. It is also possible to have different designs Homogenizers, e.g. Orifices or jet dispersers to integrate.
