Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an IAI body pump that can be advantageously used for pumping various types of fluids.

In order to obtain an inexpensive and reliable pump Yr, it has already been proposed to use an elastic tube with a reinforcing thread embedded therein extending in a helical form. The pump is equipped with two check valves as an outlet valve and an outlet valve. Pumping is accomplished by varying the length of the tubular member. To do so, one end of the card member should be fixed to the bottom of the well by means of a soft l1fil or clamped to the wall of the well, with the other end phantom! 'It's done.' Both of these methods of pump fixation are disadvantageous. The use of heavy I makes it difficult to handle the pump since the weight is small. And in many cases it is impossible to mount the pump on the wall of the well.

The purpose of this invention is to provide an inexpensive, reliable and lightweight
Another object of the present invention is to provide a fluid pump that does not have a core that is fixed in space.

Thus, the present invention provides a tubular section enclosing a pumping chamber, fourteen inlet valves through which fluid is directed into the pumping chamber, an outlet valve through which fluid is pumped out of the pumping chamber, and a pumping chamber. and actuating means for moving the first end of the tubular member relative to the second end of the card member to achieve the Ir1i
The tubular member is made of an elastic material, and within the elastic material,
In a fluid pump in which a reinforcing thread extending in a helical manner is embedded along a tubular member, a second tubular thread having one end connected to a first end of the tubular member is connected to a first end of the tubular member. A tubular member of ft is made of an elastic material, and a reinforcing thread extending from the helical r is embedded in the elastic material along the second r-shaped member. The second ends of the tubular member and the second tubular member are located at a constant distance from each other, and the interior of the second vessel H is connected to a variable B-force fluid pressure source. A fluid pump is provided with a % characteristic.

Embodiments of the present invention will be described in detail below with reference to the drawings.

The flow pump illustrated in Figure #1 has a first end piece 32 and a second end piece 31 with a separated tubular portion 31. The interior of the tubular member 3/ forms a pump chamber. The west bank is
An inlet valve 3S is provided in the inlet passage 36 through which fluid to be pumped enters the pump chamber. The outlet valve 37 is placed in the outlet passage 3g and fluid is delivered from the pump chamber through the outlet passage 3g to a conduit 39 leading to a suitable delivery cavity. The first end piece 3.2 is provided with a thread 33, which connects with the thread 26 in the first end piece 2S of the tubular member 21. The tubular member 21 further carries a screw end piece, 2.2, which carries a screw, 23, associated with the nut, 2. Saki-ii or end pieces of tubes and tubular members. 2.2. ．． ? In order to keep the drums at a certain distance from each other, the drum is installed between the drum, Kata J4I and Naratokoq. The interior of the tubular member, 2/, is connected via a conduit 13 to a fluid pressure source of variable pressure, 2/.

The tubular member 2/ (which is also valid for tubular member 3) is from the tube lI/ to f! 9. The reinforcing thread is embedded in this. The thread 11.2 runs helically along tl with a pitch angle of ■. If the thread has a length of Kg in two directions and a pitch angle of V arccot %rr (~35.3°), the length of the tubular member will decrease due to the pressure inside the tubular member. An increase in volume occurs. On the other hand, if the pitch angle v is smaller than the above-mentioned value, a reduction in length will result in a reduction in volume.

Pumping is accomplished by pressurization and depressurization inside the tubular member 21. As a result, the first part of the tubular member 21
The end piece 2S moves relative to the second end 322. Tubular member 3
The first @ piece 32 of the tubular member-1 moves together with the end piece 2S of the tubular member-1. In this way, the length and hence the volume of the tubular member 31 is varied to achieve pumping.

In FIG. 43, an alternative connection between the tubular member 2/ and the tubular member 31 is illustrated. Both members are formed from a common g4Ii. A cylindrical piece 3 is inserted into the tube and tightened in place w by a ring ++.

The second end 322 of the tubular member 2/ and the second end piece 34 of the tubular member 31! The distance between can be adjusted by Natsu), 24<. This method allows adjustment of the pump for pump delivery that varies the back pressure in the conduit 39.
