- the Guide rod 135 and the valve through hole 141 have same ellipsoidal cross-section so that valve 140 does not is rotated, but can perform a linear reciprocating motion.
- an inclined valve surface 145 formed that of the first inclined surface 137a of the contact piece 137 and the second inclined surface 139a of the contact ring 139 corresponds.
- a first space 113a is formed on the Hydraulic pressure in the inlet pipe 113 acts, and between a second End face 143 of valve 140 and one described below Valve cover 150 formed a second space 115 on which the Hydraulic pressure in the outlet pipe 115 acts.
- the valve cover 150 which consists of a non-magnetically conductive Material like plastic is made over Valve actuation opening 119 of the housing 110 attached.
- the Valve cover 150 covers the second end side 143 of valve 140 and one end of the guide rod 135 passing through the valve 140 extends and is exposed to the outside of the housing 110. How As described above, the second space 115a into which the fluid is introduced from the outlet pipe 115, between the valve cover 150 and the second end side 143 of the valve 140 defined.
- the outer cover 160 is on a portion of the housing 110 mounted, which is arranged outside the valve cover 150, and A control unit 163 is arranged in the outer cover 160.
- the Control unit 163 comprises a cable connection section 164, one A plurality of electric cables 163 and a leaf spring switch 166.
- the leaf spring switch 166 is in the vicinity of the valve cover 150 arranged and is switched on / off. This will be done later described in more detail.
- the automatic pump comprises a first means which the leaf spring switch 166 on and off.
- the first means forces valve 140 to be linear Movement so that the valve 140 on the contact piece 137 and the Contact ring 139 of the guide member 130 abuts when no fluid through the outlet pipe 115 is ejected.
- the first is Means a first magnet 171 which on the second end side 143 of the Valve 140 is arranged and moves in the same way as that Valve 140.
- valve 140 The function of the valve 140 and the first means follows described in more detail with reference to FIGS. 4a and 4b.
- valve 140 by the force of attraction between the am Valve 140 arranged first magnet 171 and the one magnetically conductive material manufactured housing 110 its State from that shown in Fig. 4b to that in Fig. 4a shown state.
- inlet pipe 113 and outlet pipe 115 are apart disconnected, and at the same time the leaf spring switch 166 is turned off, to stop the operation of the engine 125.
- the valve 140 of the automatic pump 100 according to the present Embodiment, the second end face 143 has a larger area than the first end side 142. So if the pressures in the inlet pipe 113 and in Exhaust pipe 115 become the same height, the valve 140 due to the Difference in the areas of the two end sides of the valve 140 slightly be returned to its original state.
- the automatic pump 100 is constructed so that when the valve 140 and the guide member 130 abut each other, the second end side 143 of the valve 140 in the valve actuation opening 119 is located, so that the valve easily is pressed.
- the housing 110 has chamfered flat corners 110a and 110b that coincide with same inclination with respect to the first inclined surface 137a of the Contact piece 137 and the second inclined surface 139a of the Contact rings 139 of the guide member 130 are arranged.
- the opposing arrangement of flat corners 110a and 110b first inclined surface 137a of the contact piece 137 and the second inclined surface 139a of the contact ring 139 of the guide member 130 minimizes the resistance of the fluid and thus maximizes the amount of the sucked and expelled fluid.
- the inclined valve surface 145 is the valve 140 therefore at the same inclination as the first inclined surface 137a of the Contact piece 137 and the second inclined surface 139a of the Contact rings 139 performed so that they are close to each other can.
- valve 140 can be positioned without directional restriction, since the first magnet 171 is able to force the valve 140 in to move his starting position. This means that the valve 140 in vertical, horizontal or oblique direction can be installed.
- 5a and 5b are enlarged representations of a cross section of a valve in an automatic pump after another Embodiment of the present invention is used, and clarify the construction and operation of the automatic Pump. The following is just the difference between the present embodiment and the first embodiment described.
- An elastic member 181 such as a spring is between the Valve cover 150 and the second end side 143 of the valve 140 arranged. If no fluid is expelled from the outlet pipe 115 the elastic member 181 forces the valve 140 to be linear Movement so that the inclined valve surface 145 of the valve 140 on the first inclined surface 137a of the contact piece 137 and the second inclined surface 139a of the contact ring 139 of the guide member 130 is applied.
- the elastic member 181 continues to support the valve 140 elastic in such a way that the inclined valve surface 145 of the Valve 140 fixed to the first sloping surface 137a of the contact piece 137 and the second inclined surface 139a of the contact ring 139 of the Guide member 130 abuts.
- 6a and 6b are enlarged representations of a cross section of a valve in an automatic pump after another Embodiment of the present invention is used, and clarify the construction and operation of the automatic Pump. The following is just the difference between the present embodiment and the first embodiment described.
- a second magnet 185a is near the first end side 142 of the Valve 140 is arranged, and a third magnet 185b is in the foot 133 of the Guide member 130 arranged.
- the second magnet 185a and the third magnet 185b arranged so that their opposite polarities are so arranged side by side that an attractive force acts between the magnets. Work through it the second magnet 185a and the third magnet 185b together to to force the valve 140 to move linearly so that the oblique valve surface 145 of valve 140 on the first oblique Surface 137a of the contact piece 137 and on the second slope Surface 139a of the contact ring 139 of the guide member 130 rests, when no fluid is discharged through the outlet pipe 115.
- the second magnet 185a and third magnet 185b continue to assist the valve in such a way that the inclined valve surface 145 of the Valve 140 fixed to the first sloping surface 137a of the contact piece 137 and the inclined surface 139a of the contact ring 139 of the Guide member 130 abuts.
