The pumps are valve-controlled, self-priming radial piston pumps with fixed displacement. They consist essentially of the housing (1), eccentric shaft (2) and pump elements (3), with suction valve (4), pressure valve (5) and piston (6). Suction and displacement process Pistons (6) are arranged radially to the eccentric shaft (2).

Radial piston motors - HAWE Hydraulik

Radial piston motors with external pressurization: In this case, the stroke movement is created by an eccentric tappet on the drive shaft. Each piston therefore only performs one stroke/rev. The large displacement (torque) is achieved here using large piston diameters. The oil is distributed via control rings in the shaft extension (Figure R 3).

Designing a hydraulic pump as an internally driven radial piston pump, driven by an eccentric, for example, is inexpensive because a reduced number of component parts is needed, thereby diminishing the assembling effort. In addition, it is possible to use low-cost pump …

Radial piston pump type R and RG - HAWE

1.3 Design The radial piston pumps are valve-controlled with cylinders in a radial arrangement. The cylinder radials, arranged in one, two or more superimposed layers (rows), are driven by bearings 6tted eccentrically on the drive shaft (piston pressure stroke), and reset by springs (piston suctionnstroke).

Radial piston pump - Machine Drawing

Figure 3-15 shows a nine piston, radial piston pump. When a pump has an uneven number of pistons, no more than one piston is completely blocked by a pintle at one time, which reduces flow pulsations. With an even number of pistons spaced around a cylinder block, two pistons could be blocked by a pintle at the same time.
