Piston pump works with a plunger to introduce the principle of a two-way valve on the piston, and the direction opposite RK series radial pump, cylinder plunger pump appear negative radial movement in one direction , then a one-way valve is opened liquid is drawn cylinder, radial pump price movement of the plunger in the other direction, the liquid compression after another one-way valve is opened, liquid is sucked into the cylinder is discharged. This way of working continuously after the formation of a continuous oil movement. Plunger up oil, when up to a chute (stop for the edge) on the plunger hole on the sleeve and back the same, then low pressure oil pump oil chamber and piston head in the hole and radial holes and chutes communication, a sudden drop in oil pressure, the oil valve closed quickly to stop the oil under the action of the spring force. Since then even up the plunger, when the raised portion of the cam turn over, under the action of the spring plunger downward again. At this time began the next cycle. Piston pump with a piston as described principle, a two-way valve on the piston, and in the opposite direction, negative pressure occurs when the cylinder piston motion in one direction, then a one-way valve opens the liquid is sucked After the cylinder, the plunger movement in the other direction, the liquid compression another one-way valve is opened, liquid is sucked into the cylinder is discharged. This way of working continuously after the formation of a continuous oil movement.
