Definitions

  • the invention relates to a feed pump, in particular for paints and similar media, consisting of an insertable in a reservoir, provided with an inlet valve and an outlet valve and a cylinder arranged therein by a motor such.
  • a feed pump in particular for paints and similar media, consisting of an insertable in a reservoir, provided with an inlet valve and an outlet valve and a cylinder arranged therein by a motor such.
  • B. via an eccentric lever or crank drive driven pump piston, the conveyed medium via a riser pipe connected to the valve housing receiving an outlet pipe can be fed.
  • the Japanese utility model Sho-61-200182 discloses a feed pump of this type, by means of which the medium to be processed can be fed to a paint roller from a storage container.
  • the riser pipe is formed by connecting pieces formed on the valve housing of the outlet valve and the outlet pipe and an intermediate piece placed thereon. Apart from the fact that both the connections between the nozzle attached to the valve housing and the intermediate piece and also between this and the nozzle provided on the outlet line are to be sealed to compensate for a lateral offset of the connecting pieces which are not aligned with one another by the intermediate piece.
  • the object of the invention is therefore to design a feed pump of the type mentioned at the outset in such a way that it can be used for differently high storage containers for their complete emptying without the delivery capacity being impaired.
  • the adaptation to the respective height of the storage container should be able to be carried out in a very simple manner and in a short time, but nevertheless a secure locking of the individual components and thus a reliable function of the feed pump should be ensured and this should be easy to dismantle in order to its components without difficulty to clean and / or replace wear parts if necessary.
  • the construction effort should be kept low, and the feed pump should also be able to be manufactured in an economical manner.
  • this is achieved in a feed pump of the aforementioned type in that, in order to change the length of the riser, it is formed from two or more mutually adjustable sections which can be locked at different altitudes, or in that the riser consists of two nests which can be plugged into one another and locked together Sections exist, of which at least one is optionally of different lengths.
  • the adjusting lever should be provided on the side opposite the latching lug with an angled molded grip.
  • the connecting piece forming the riser rotatably, for. B. by means of a protruding from the cylinder and in a machined in the outer surface of the attached to the outlet pipe longitudinal groove engaging web
  • the piston rod assigned to the pump piston should be connectable to the drive member of the engine at different altitudes or alternatively be replaceable by a piston rod compensating for the change in length of the riser.
  • outlet pipe, the riser pipe and the cylinder firmly connected to the housing of the outlet valve and the pump piston used in these by means of a cover, a plate or the like provided on the outlet pipe.
  • B. by means of a federal government to hold the reservoir, and to provide the lid or plate with a guide piece for the piston rod connected to the pump piston.
  • a filter can be removed from the cylinder in the direction of escape of the pump piston, preferably by means of a bayonet catch, and the outlet line with molded cover, the components of the riser pipe and the cylinder with molded valve housing can be made of an impact-resistant plastic.
  • a feed pump is designed according to the invention in which the riser assigned to it is adjustable in length, it is possible to adapt the feed pump to storage containers of different heights and to suck in the liquid to be conveyed in each case in the base region of the storage container without impairing the pumping behavior of the pump becomes.
  • the length of the riser By changing the length of the riser, the distance between the feed pump and the outlet line can be changed without difficulty, the feed pump can thus be easily inserted into storage containers of different heights.
  • the riser consists of only two components and that the resulting annular gap in the connecting piece forming the riser is easy to seal.
  • the nozzles are through the on the valve housing of the exhaust valve or the control lever attached to the outlet pipe is locked in a reliable manner, but this connection can be released easily and in a short time in order to lengthen or shorten the riser pipe.
  • the feed pump is therefore easy to dismantle, so that its components can be cleaned easily and / or wear parts can be easily replaced. A high level of operational reliability and versatility are therefore always given.
  • the feed device shown in FIGS. 1 and 2 and designated 1 serves to supply a hand tool, for example an internally fed paint roller or a brush, with the medium to be processed and essentially consists of a storage container 2 designed as a lower part for receiving the medium and one with the reservoir 2 detachably connected upper part 3, in which a handle opening 4 is formed for transporting the power supply 1.
  • the medium is fed to an outlet line 20 by means of a feed pump 11, to which a line leading to the hand tool (not shown) can be connected.
  • the feed pump 11 has a cylinder 12, in the cylinder space 13 of which a pump piston 14 is inserted, and an inlet valve 18 and an outlet valve 19.
  • the inlet valve 18 is inserted directly into the correspondingly designed cylinder 12, the outlet valve 19, however, in a valve housing 17 attached to the cylinder 12, which is connected to the outlet line 20 via a riser pipe 21.
  • an electric motor 41 is provided, which can be switched on and off by means of a switch 5 mounted in the upper part 3 and is supported in partition walls 6 and 6 ′ of the upper part 3.
  • the electric motor 41 is drivingly connected to a piston rod 15 of the pump piston 14 via gear wheels 42 and 43 and an eccentric lever 44.
  • the riser 21, 21 ' is designed to be variable in length.
  • connecting pieces 22 and 23 or 22 'and 23' are attached to the valve housing 17 and the outlet line 20, which are adjustably arranged one inside the other and can be locked at different heights.
  • An adjusting lever 25 or 25 ' is used for this purpose, which is formed on the valve housing 17 according to FIG. 3 and on the outlet line 20 according to FIG.
  • the actuating lever 25 or 25 ' which is pretensioned against the socket 23 or the socket 22', has a latching lug 26 which optionally engages in notches 28, 28 'or 28' 'incorporated in the socket 23 or socket 22' can.
  • the adjusting lever 25 or 25 ' is equipped with a handle 27 in order to be able to push it off and thus to release the locking mechanism.
  • a web 29 is formed on the cylinder 12, which engages in a longitudinal groove 30 machined into the connecting piece 23, in the embodiment variant according to FIG 4, on the other hand, a web 29 'is attached to the nozzle 23' and is guided in a longitudinal groove 30 'of the nozzle 22'.
  • the piston rod 15 is provided with three suspension eyes 16, 16' and 16 '' for the eccentric lever 44, which are spaced apart from one another are arranged, which correspond to the distances of the notches 28, 28 'and 28' '.
  • the position of the pump piston 14 can also be adapted to the respective length of the riser 21.
  • the feed pump 11 is interchangeably inserted in the reservoir 2 in the embodiment shown.
  • it is provided with an opening 7 and a plate-like cover 31 is formed on the outlet line 20 and has a circumferential collar 32 which engages in the opening 7.
  • a guide piece 33 for the piston rod 15 of the pump piston 14 is attached to the cover 31.
  • the distance between the filter 45 to be arranged in the bottom area of a storage container 2 and the outlet line 20 and thus the length of the riser 21 '' can also be changed, as shown in the feed pump 11 '' according to FIG. 5, in that at least one of the connecting pieces 22 ′′ and 23 ′′ forming these and the possibly associated components can be dimensioned optionally of different lengths.
  • This possibility of changing the length of the riser 21 ′′ is illustrated by the dividing lines drawn in.
