Definitions

  • the invention relates to a suction-pressure pump for ejecting a product from a container, with a housing in which an axially drilled piston Sealed axially via a first housing section is displaceable, with a piston bore continuing hollow piston rod, which is in an opening of a Closing hood of housing and container movable is and on its free end a tightly fastened Actuating head, by the actuation of the Piston against the force of a return spring to an am Housing provided connection piece for a dip tube is pressed while in a pressure chamber of the housing builds up a pressure, which is a first valve closure piece in the connecting piece against a first valve seat presses, the actuator head of a to the Bore subsequent outlet channel via a check valve up to an ejection opening for the product is interspersed with at least one opening in one second housing portion between the first housing portion and the closure hood.
  • a known suction-pressure pump of this type according to the preamble of claim 1 as in DE 27 09 796 B2 can, although in upright normal position, in the Actuator head is higher than the connection piece, suck in the product from the container as well spend by a pressure stroke.
  • a reverse Attitude i. Overhead posture
  • the product could however not be sucked out of the container as soon as the level in the container in the overhead pose deeper as the suction opening of the dip tube (also called "suction tube”) called) is located.
  • the product issue would be in the Overhead posture only possible if previously in normal posture a suction stroke was performed.
  • the invention is therefore based on the object, a Specify suction-pressure pump of the type mentioned, which also in an overhead attitude at a level of the product in the container, which is lower than the suction port the immersion tube is the product of the Can suck in and spend container.
  • this object is achieved by claim 1, characterized in that the piston in the unactuated state under the return spring force a passage between the pressure chamber and the or each opening in the second housing section releases and the connecting piece a second valve seat and a second valve closure piece, the in an attitude of suction-pressure pump, in which the actuator head lower than the connecting piece is, assumes its closed position on the second valve seat and in a reverse attitude, in which the actuator head higher than the connecting piece is, its opening position occupies.
  • the product is in an overhead posture over the opening or openings in the housing wall and the passage during the suction stroke of the pump in sucked in the pressure chamber, and then during the pressure stroke to be issued.
  • the suction pressure pump can therefore both upright and upside down Aspirate and dispense the product.
  • the illustrated suction-pressure pump 1 is on the edge the opening of a container 2 over an intermediate arranged sealing ring 3 tightly fastened.
  • the Suction-pressure pump 1 has a hollow cylindrical housing 4, the lower end by a check valve with a first valve closure piece 5 in the form of a ball can be locked.
  • the valve closure piece 5 is seated in his illustrated in Fig. 1 lower layer on a Valve seat 6 tight.
  • In the housing 4 is a hollow cylindrical piston 7, against the inside of the Housing 4 sealed in a first housing portion 4a, axially displaceable.
  • the bore of the piston 7th is set in a piston 7 integrally formed on the hollow piston rod 9 continues.
  • the piston rod 9 is in an opening 10 an upper closure cap 11 of the housing. 4 and container 2 sealed displaced.
  • Piston rod 9 On the free end of the protruding from the housing 4 Piston rod 9 is an actuating head 12 of the suction-pressure pump 1 tight and firmly attached.
  • the operating head 12 passes through an outlet 13, which is at the hole 8 connects.
  • the outlet 13 is set via a check valve 14 with a valve closure piece 15 and a return spring 16 to an ejection opening 17 in an insert 18, the one in the Ejection opening 17 has vortexing vortex chamber, continued.
  • the valve closure piece 15 is made of rubber-elastic Material, here an elastomer, and has a cylindrical Body, which is about in its axial center surrounded by a sealing lip 19.
  • the sealing lip is below one caused by its inherent elasticity Spring force on the inside of a coaxial with the Piston rod 9 extending first portion of the outlet channel 13 and locks in the unactuated state of the actuating head 12 extending transversely to the first second section of the outlet 13th
  • the piston 7 is in its unactuated position after the Fig. 1 and 2 with a circumferential at its free end Sealing lip 20 closely to the inside of the housing. 4 at.
  • a surrounding the piston 7 above the sealing lip 20 Bund 21 serves to guide the piston during his movement, but leaves a game between them and the inside of the housing 4 free.
  • a return spring 22, which is shown interrupted, is supported on the one hand in the piston 7 at the bottom of an annular space 23, the from the outer wall of the piston 7 and a pipe socket 24 is limited, and on the other hand on a shoulder 25 in the housing 4 from.
  • the housing 4 has the lower in Fig.
  • valve head 12 Upon actuation of the valve head 12 at the in 4 illustrated attitude of the suction-pressure pump 1, until the sealing lip 20 exceeds the gradation 27, in turn, in turn, the first valve closure member. 5 pressed against his seat 6 and the product 36 from the Pressure chamber 26 via the bore 8, which now opened again Valve 14 and the outlet channel 13 ejected.
  • the suction-pressure pump 1 can therefore be in any Holding suction and pressure strokes until the container is emptied 2 execute.
  • a modification of the illustrated embodiment may for example be that the grooves 33rd omitted and instead the openings 32 to the lower end in Fig. 1 of the grooves 33 are extended. The passage would then in the position of the piston. 7 2 released directly through the openings 32.
  • the grooves 33 have the advantage that the housing portion 4c remains stable and hardening its plastic mass in the production not worth mentioning warps, as in the housing section 4c reaching openings 32 could be the case. Between the housing 4 and the piston 7 is therefore on the entire piston stroke ensures intimate contact.
