Embodiment
Be designed to comprise the reciprocating piston pump of magnetic driving equipment, also referred to as the liquor pump 1 of solenoid pump, there is a pumping cylinder 2 around pump chamber 3.The outlet side of described pump chamber 3 is limited by an exit orifice 4, and described exit orifice is arranged in the bottom 5 of pumping cylinder 2.On bottom 5, form a connection socket 6 away from pump chamber 3, described exit orifice 4 passes in connection socket.This connection socket has an internal thread for Bonding pressure pipeline.One piston 7 snaps in pump chamber 3 from water intake side.This piston is molded on an armature 8 in an illustrated embodiment.This member being comprised of piston 7 and armature 8 is made by the ferromagnetic material of stainless steel quality.This member runs through inlet channel 9, the corresponding armature 8 of the first inlet channel section 10 wherein, and the corresponding piston 7 of the inlet channel section 10.1 being attached thereto.In an illustrated embodiment, the internal diameter of channel section 10 is greater than the external diameter of the inlet channel section 10.1 of piston 7.In the member being formed by piston 7 and armature 8, three ring weeks distribute, and the pressure compensation opening of arranging in the mode that angular distance is identical is to each other contained in the piston side front 11 of armature 8, described pressure compensation opening connects the piston side of armature 8 and its (comprising entrance channel section 10.1) inflow side.Owing to being sectional drawing, in Fig. 1, only can see two 12,12.1 in three pressure compensation openings.
Plunger armature member shown in Fig. 1 is not a part of the present invention, and is intended to explanation for realizing the working principle of the piston side of armature 8 and the plunger armature member of the pressure balance channels between its inlet side.In the present embodiment, the inlet side of described armature 8 is inlet channel sections 10.1.The vibratory shaft that the longitudinal axis of described pressure compensation opening 12,12.1 is parallel to member extends.Hole 12,12.1 is close to the shell surface of piston 7 diametrically.The diameter of inlet channel section 10.1 is greater than the external diameter of piston 7.Therefore, described pressure compensation opening 12,12.1 passes in inlet channel section 10.1 when parallel aligned.
The shell surface of piston 7 is isolated to form the mode of a labyrinth and the inner side of pumping cylinder 2.By these two energy, along y direction, towards a very narrow gap between the member moving each other, realize this point.Thereby between the outer wall of piston 7 and the inwall of pumping cylinder 2 without extra Sealing.This turns round while also making described piston 7 carry out oscillating movement in pump chamber 3 glibly.Described plunger armature member is guided by the piston section that snaps in pumping cylinder 2 in its oscillating movement.Due to above-mentioned Sealing, avoided the swing of plunger armature member.
Piston side in armature chamber is partly provided with a damping spring 18.This damping spring is maintained at an outside and is molded between the flange 19 and positive 11 on pumping cylinder 2.
On armature housing 13, cover has an electric solenoid unit.The structure of described solenoid unit and design are intended to produce periodic magnetic field.When having produced magnetic field, this magnetic field will make the power motion of armature 8 counter pressure springs 14, thereby and piston 7 is pulled out when the volume of pump chamber expands from pumping cylinder 2.When interrupt in magnetic field, energy stored in described pressure spring is also pressed into piston 7 armature 8 in the position shown in Fig. 1 thus again.For producing periodic magnetic field, described solenoid unit is assigned with and is connected with a diode, thereby only when one of two alternating voltage polarity, produces described magnetic field.In this way, the longitudinal axis of the relative pumping cylinder 2 of described plunger armature member and armature chamber, vibrates along y direction with the frequency of alternating voltage.
For the oscillating movement by piston 7 is delivered to water outlet side by liquid from the water intake side of pump 1, piston 7 is equipped with an one-way valve without spring as inlet valve 21 on it gos deep into the end of pump chamber 3.When piston moves towards inlet side direction, this inlet valve is opened.When move along opposite direction in the bottom 5 of present dynasty's pumping cylinder 2, valve 21 is closed.In exit orifice 4, be equipped with second without spring non-return valve as outlet valve 22.Two valves 21,22 adopt identical design in the embodiment shown.The valve of the same type of valveless spring has the guiding section being connected with its valve body, described guiding section conventionally with the manufacture of valve body integrated type.Described guiding section runs through ring-shaped valve seats, and the in the situation that of inlet valve, stretches into the inlet channel of piston.The in the situation that of outlet valve, described guiding section stretches in the exit orifice around the pumping cylinder of pump chamber.When initial situation is valve while being arranged in closed position, described guiding section can move vertically to open valve in inlet channel and exit orifice, and is connected to securely respectively on corresponding member (piston and pumping cylinder).Described valve so arranges along the distance of y direction mobility, makes when valve body is lifted from valve seat, and the cross-section area of opening is enough to by the required water yield.The pressure reduction that utilization produces in system side due to the water intake side of valve body and the piston movement between its water outlet side moves in closed position corresponding valve body.At this liquor pump, be applied to household electric appliance, for example, in the situation in coffee machine, what at the inlet side of inlet valve, exist is external pressure, is under any circumstance less than the pressure of pump machine total head.When piston has completed its return stroke towards the exit orifice of pumping cylinder under the effect of the power of pressure spring, described inlet valve closes.In this movement process, in pump chamber and the pressure that exists of the outlet side of inlet valve valve body higher than inlet side, thereby cause described valve because of the motion of piston and follow the current of this motion automatically to be closed.With regard to outlet valve, this valve is passed the liquid that exit orifice extrudes and opens, and automatically closes by the reverse pumping campaign of piston.By following the expansion of the pump chamber volume of this motion, the fluid pressure that acts on the outlet side of described outlet valve valve body is greater than inlet side.
According to this design proposal, at least one in two valves is connected to that to form the member (piston and/or pumping cylinder) of valve seat upper, even thereby do not adopt valve spring can normally work yet, this design proposal has significantly reduced and has formed the required number of components of valve.Except forming the member of valve seat, only need in principle another member, i.e. valve.In addition in this design proposal, there is not, the functional affected danger due to valve spring fracture of oil hydraulic pump.
According to a kind of preferred design proposal, described inlet valve and/or outlet valve have a guiding section, for connecting corresponding member (piston and pumping cylinder), and the segmentation on ring Zhou Fangxiang of described guiding section.Each is guided section segmentation and with through-flow gap, separates to each other.Wherein at least one guiding section segmentation has one radially towards the interlock lug of outer lug, and described interlock lug is a stop surface towards the face of valve body.The stop surface acting in conjunction of this stop surface and a member side, for limiting the motion amplitude of opening of valve.The stop surface of described member side for example can by one ring week groove form, for preferred this structure of inlet valve.This groove is arranged in the internal valve of piston inlet channel.For outlet valve, at least one interlock lug can tip upside down in exit orifice and snap in pump chamber thus.
For reducing costs, can use plastics, for example by Shooting Technique, manufacture aforementioned valve.If do not wished, adopt plastics, described valve can be by metal, and for example a kind of applicable brass alloys are made.The application of valve 21,22 also can be independent of concrete described reciprocating piston pump in the embodiment of Fig. 1, and is independent of the design of concrete described plunger armature member in these design proposals.
