Definitions
- the present invention relates to a motor pump with axial flow through with incorporated flow meter and pressure switch.
- a coffee machine comprising a motor pump associated with a pressure switch mounted on the supply circuit and making it possible not only to control the water supply system, but also to remove the reservoir for the fill thanks to the fact that said pressure switch consists of two couplable elements fixed one on the chassis of the machine and the other at the base of the tank, each of these two elements being closed automatically when they are separated.
- the fixed element is connected to the motor-driven pump and is fitted with a flexible membrane acting on an electrical contact according to the pressure variations caused by changes in the level of the water in the tank.
- the liquid entering this element leads to a single chamber in which the flexible membrane and the outlet orifice towards the motor pump are located. This arrangement causes, under certain conditions, an aberrant operation of the electrical contact, in particular when the motor pump stops and starts.
- the device according to the present invention relates to the production of a motor pump incorporating all of the liquid flow control devices and connected to a particularly reliable supply pressure switch.
- a motor pump with internal axial flow, with an electromagnetic motor and hollow free piston, equipped with a built-in flow meter and flow limiter, and associated with a pressure switch intended to control its supply and comprising separate internal paths for the flow of liquid leading to the motor pump and for connection to a chamber containing a flexible membrane actuating an electrical contact for controlling the power supply to the motor pump.
- FIG. 1 is an axial section of the motor pump with built-in flow meter and pressure limiter
- FIG. 2 is a cross section along the arrows F1 of Figure 1
- Figure 3 is an enlarged front view of the paddle wheel of the flow meter
- Figure 4 is an axial section along the arrows F2 of Figure 3
- Figures 5 and 6 are axial sections of the two separate elements of the pressure switch and FIG. 7 shows, under the same conditions, on a different scale, these two elements assembled.
- the device consists of a motor pump 1 for supplying liquid consisting of a monobloc assembly comprising a flow meter 2 and a pressure limiter 3 integrated. It is preferably of the hollow free piston type with an electromagnetic motor, but may also be of the controlled piston type driven by a rotary motor. In the first case, it advantageously consists of a main body 4, machined in one piece of plastic, one of its. ends forming the coil 5 of the electromagnetic motor, the other end containing the cylinder block 6 in which the piston 7 moves, and comprising non-return valves 8 and 9.
- the flow meter 2 located in a block closing the main body 4 on the opposite side of the cylinder block 6, directly after the water inlet 10 (FIG. 2), is formed by a idler wheel 11 with paddles and comprises one or more permanent magnets 12, the passage of which is detected by an electromagnetic detector 13, having the dual function of making it possible to stop the motor pump once the desired quantity of water has been obtained, and to signal a possible fault in the water supply.
- the pressure relief valve 3 consists of a bore in the cylinder block 6 containing a calibrated spring valve placing the water outlet 14 in communication with the base of the piston 7, so that the water is recycled, without driving flow meter 2 in the event of back pressure at said water outlet.
- the arrangement of the water inlet 10 and the flow meter 2 opposite the water outlet 14 causes the water to pass through the driving part of the pump, along the axis of the latter, this which allows a direct flow significantly improving the operation and reliability of the pump as tests have demonstrated.
- the motor pump 1 will advantageously be associated with a pressure switch 20 mounted on the liquid supply circuit (FIGS. 5 to 7).
- This pressure switch will consist of a fixed element 21, integral with the motor pump 1 or the chassis carrying the latter, and a nozzle 22 mounted at the base of the reservoir 23 and communicating with it. These two elements constituting a quick coupling which can be uncoupled so as to make the tank removable without tools.
- the fixed element 21 comprises an electrical contactor 24 formed by two electrodes and a flexible membrane carrying a conductive plate normally spaced from these electrodes by an elastic device and establishing contact between them when the weight of the liquid present in the reservoir 23 repels the flexible membrane, the decrease in pressure caused by the drop in level in the reservoir having the opposite effect by spreading the membrane and the conductive plate of the electrodes, which cuts the contact.
- This device constitutes a very reliable means of controlling the automatic feeders of the machine.
- the flow of liquid entering the pressure switch 20 is divided into two parts directed respectively to the chamber 25 containing the flexible membrane of the contactor 24 and towards the outlet orifice 26 of the pressure switch. This is obtained by two paths: on the one hand a central path 27 leading to the chamber 25 and, on the other hand, a peripheral path 28 leading to the outlet orifice 26. These two paths are separated by a hollow part 29 disposed in the body 30 of the fixed element 21 and extended by a socket 31 located in the end piece 22.
- the sleeve 31 is axially movable and associated with a spring so as to close the peripheral path 28 during the separation of the fixed element 21 and the end piece 22, the central path 27 being closed by a valve 32 also moved by a second spring, and sliding in the sleeve 31.
- the fixed element 21 is further provided with a cylindrical shutter 33 intended to isolate the liquid circuit communicating with the motor pump 1 so as to prevent the liquid remaining in the latter from flowing outside, this shutter sliding at the exterior of the hollow part 29 and being actuated by a third spring.
- the sealing of the assembly is ensured in a known manner by a series of O-rings 34 resting on seats provided for this purpose.
