Definitions
- the present invention relates to a radial pump comprising a body in which is rotatably mounted a shaft carrying at least one eccentric or a control cam and one or more pistons arranged radially around the eccentric or the cam.
- a pump of this kind which can comprise at will one, two or more pumping units, which makes it possible to adapt the pump to the needs of use and thus to manufacture this pump in large series, at a price of returns reduced.
- the pump according to the invention is characterized in that the pump body is provided with a series of radial bores arranged circumferentially around the cam or of the eccentric and in that each bore can receive at will either a plug of shutter, an independent pumping unit comprising an outer jacket, a piston slidably mounted in the sleeve, a return spring tending to apply the piston on the cam or the centri f q ue, and a discharge valve.
- each bore is fitted with a plug or a pumping unit.
- the pumping unit or the plug can be held in position by a metal rod.
- the element is thus removable and it is possible, if desired, to replace a pumping unit with a plug, or vice versa.
- the jacket of the pumping units and the caps bear grooves which, when a pumping unit or a goat is placed in a bore, are located opposite a groove of this bore, constituting a toric cavity, a plastic rod being cast in the cavity , after installation.
- the entire pump is permanently mounted.
- the various toric cavities are preferably connected to the same supply duct opening to the outside by a pouring nozzle.
- the pump according to the invention comprises a body 1 in which is rotatably mounted a shaft 2 carrying an eccentric 3; on this are mounted a ring 4 in bronze and a wear ring 5 in steel held by two washers 6.
- the shaft 2 rests on two plain bearings mounted one directly in the housing, the other in a ring 7 forming a spacer.
- the portion of the shaft located beyond this ring passes through a sealing jcint 8 and carries a drive pulley 9.
- the annular chamber 10 which surrounds the eccentric 3 is connected to a supply duct 11. It is moreover connected by a bore 12 of the shaft to a chamber 13 provided at the end of the shaft in the body 1 and ensuring the lubrication of the end bearing.
- the body 1 has radial bores la which communicate with the annular chamber 10 and can either be closed by plugs, or carry a pumping unit 31.
- the body is provided with two bores, each of which carries a unit pumping.
- Each paging unit includes a jacket 14 which is engaged in one of the bores la. It can be in abutment on the ring 7 or have a shoulder in abutment on the pump body 1. Its cylindrical part of reduced diameter is provided with a first groove containing an O-ring seal 15 and a second groove arranged opposite a second complementary groove provided in the bore la. The assembly of the two grooves constitutes a toric cavity which is connected by a conduit 16 to a pouring nozzle 17. After fitting the jackets 14 of the pumping units in their bores, a plastic material was poured into the nozzle 17; this plastic material filled the toroidal cavities and formed in each of them a rod 18 which definitively fixes the jacket 14 in its bore.
- a piston 19 consisting of a blind tube whose closed face is supported on the eccentric 3.
- the cylindrical part of the piston has holes 20 uncovered or not depending on the position of the piston and adapted to put chamber 10 in communication with the interior of the piston.
- a return spring 21 which is interposed between a volume compensator 33 bearing on the bottom of the piston and a ring 22 immobilized in the jacket 14 by a metal rod 23.
- the ring 22 is pierced with an axial hole 24 and its face opposite the piston 19 forms a seat for a valve 25 which can close the hole 24.
- This valve is movable inside an opening 26 made with a milling cutter in a nozzle outlet 27 which is fitted into the jacket 14 and is immobilized in position by a pin 28.
- the valve 25 is subjected to the opposing actions of the pressure inside the piston and of a return spring 29 bearing on the end cap 27.
- the jacket 14 is immobilized by a metal rod 30. It is thus possible, if desired, to remove the jacket and replace it with a plug 32, as shown in Figure 4 Furthermore, the jacket 14 does not have a shoulder and is in abutment against the spacer ring 7.
