Abstract
In a variable flow pump an outer casing 2 has a slot through which a lever 1 joined to a cylinder 3 protrudes. The inner surface of the cylinder 3 is in one position (A) of lever 1 coaxial with a vaned rotor 6 and in another position (B) of lever 1 non-coaxial with the rotor, these positions corresponding respectively to zero and maximum flow rates and pressure of the pump. It is stated that this pump may be used to obtain a variable speed transmission when the discharge of the pump is connected to a gear pump in which the gear pump will be driven by the flow of the variable pump. At a constant speed and force the pump pressure and flow will vary depending on the position of the lever which makes it suitable to be used as a variable speed transmission. <IMAGE>
Description
[PANEL A]
VARIABLE FLOW PUMP [Technical field] This invention relate to slidingeblådes variable flow pump [Background] sliding blades pumps are will known pumps
which comprise a rotating ex-centrice desk from it's
casing with two or more sliding blades
The suction is created at the wide side of the pump
and the discharge at the narrow side. This type of
pumps have a constant flow if the speed is constant
and are used to pump liquides or to compress gasses essential Technical Features] According to the present
invention there is provided a variable flow sliding
blades pump comprising a circuler outer casing with a
slot to allow for a lever to rotate at 1800 , a free
stay cylinder with a lever passing through the
slot of the outer casing .The inner of the cylinder
is ex-centrice to it's outer liner , and a rotating
desk with a sliding blades
The variation of flow is obtined by moving the lever
from one positin to another , in which the axle position
of the cylinder is changed to the rotating desk axle
which intern changes the flow [Example] A specific embodiment of the invention will now
be described by way of example with referance to the
accompanying drawings in which :
Figuee 1 shows the pump as a complete unit
Figure 2 illustrate the different components of the
pump
figure 3 show the pump at 0% flow where the lever
at position A [PANEL B]
Figure 4 show the pump at 100% flow when the lever at
position B
Figure 5 illustrate the different parts of the pump [NB:The marginal annotations are for information . they
should not be included.]
Referring to the drawin the pump comprises a circuler outer
casing with a slot (fig 2-2) a free stay cylinder inside
the casing , the inner of the cylinder is ex-centrice to
it's outer liner (Fig 2-3) with a lever passing through
the slot of the outer casing , and a rotating desk with
four sliding blades located in the meddle of the pump
(Fig2-5,6) , the rotating desk is slightly ex-centrice to to the outer casing
(Fig2-4) indecate the suction zone in the pump
(Fig2-8) indecate the discharge zone in the pump
(Fig2-7) indecate the driving shaft
(Fig2-l) indecate the lever which is attached to the cylinder
In order to obtin the proper function of the pump , the
rotating desk must be rotated at a sufficint speed through
the driving shaft (Fig2-7) so the sliding blades will be in
direct contact with the cylinder surface (Fig2-3,5)
When the lever in position (A Fig3) the flow of the pump is 0% , as the space around the rotating desk is equal.
When the lever is shifted from position (A Fig3) to position
(B Fig4) the flow of the pump gradually increases up to 100% where the space at the discharge zone of the pump is at
smallest space.
The feature advantage of this pump is not only to obtin a
variable flow and pressure of liquiedes but it cane be used
to obtin a variable speed transmition
If the pressure of the pump increases, the flow decreases
If the flow of the pump increases , the pressure decreases.
Claims (3)
- PANEL C1CLAMES 1 A variable flow pump comprising a circuler outer casing with a slot to allow for a lever to rotate at 1800, a cylinder with a lever passing thrugh the slot of the outer casing The external diameter of the cylinder is smaller than the internal diameter of the casing, and the internal cylinder is ex-centrice to it's own--external diameter , and a rotting desk with sliding blades(four blades in this example) which is located slightly ex-centrice of the external casing , but it fall in the middel of the cylinder when at 0% flow.By moving the lever which is attached to the cylinder from one position to another, the center of the inner cylinder will change, which will create a deferential of space around the rotating desk and therefor the suction and the discharge from the pump can be created depending up on the position of the lever . when the flow of the pump increases the pressure creases, and if the flow of the pump decreases the pressure of the pump will increases at a constant speed and force input
- 2 A variable flow pump as claimed in any preceding wherein bearing means are provided on both or one end of the rotating shaft.
- 3 A variable flow pump as clamed in any preceding wherein weals means are provided for both the shaft and the slot to prevent any leaks from the pump - Avariable flow pump substantially as described herein with referance to Figurs 1-5 of the accompanying drawing
