Abstract

The invention allows to expand the functionality of the pump-pulsator. The distributor (P) 7, the sickle-shaped windows interacting with the windows of the bores 9 of the cylinder block 5, is mounted 13 connected to the movement mechanism 15. The angular size of the suction and discharge windows of the cover 8 of the housing 1 is made in accordance with the equality oJ ,, Ы + 2d, where ci is the angular size of the suction and discharge windows, oL is the angular size of the jumper P, d is the width of the suction and discharge windows. With this design, P obtains oscillatory movements relative to the neutral line through the axis from the drive mechanism, as a result of which it is possible to realize the idle mode when there is no pump output, pumping with reverse, pump-pulsating mode, or mode synthesized by 3 of these modes . 5 il.

Description

This invention relates to a mass structure and can be used to create pressure pulsations of a liquid.

The purpose of the invention is the extension. functionality by providing idle and pulsed modes.

Fig. 1 shows a pump pulsator; the general view of Fig. 2 is a schematic diagram of the pump; on, 3 dispenser in neutral mode; Fig, 4 is the same in the pump mode; Figure 5 is the same in pump-pulsation-IHOM mode.

 The axial-piston pulsator pump consists of body 1, drive shaft 2, connecting rod 3, pistons 4 blocks of q Pindrov 5, cardan b; The cylinder block rests on the end surface on the distributor 7,: installed on the lid 8 Pistons 4 | are installed in cylindrical bores 9, provided with windows U, the exit is on the front surface of the cylinder block 5 and interacting with the crescent-shaped windows 11 of the distributor 7, separated by bridges 12, {The distributor 7 is mounted on the axis 13, coupled by the coupling half 14 to the natural mechanism 15, having a cam 16..

; Axial piston pump-pulse ™ mountains works as follows.

Rotation from the drive shaft 2 through the cardan 6 is transmitted to the cylinder block 5, the pistons 4 complete the pumping and pumping cycles. Distributor} receives oscillatory movements from the yositelno neutral line by means of axis 13 through semi-coupling 14 from the drive mechanism 15. At the same time, it is fashionable to realize the idle mode

when there is no Supply at the outlet of the pump, pumping mode with reverse, pump-pulsating mode or mode synthesized from the listed modes.

The profile of the cam 16 allows various forms of oscillation to be obtained.

The frequency of the pulsations is regulated by the frequency of rotation of the drive mechanism 15, the amplitude by changing the profile of the cam 16.
