摘要： A radial piston pump has a rotor with cylinder chambers in which pistons are reciprocated by an eccentric actuator ring. A stationary centrally located control means has low pressure inlet chambers and high pressure outlet chambers connected by radial channels with low pressure ports and high pressure ports which are swept by the cylinder ports of the pump rotor. Only in the radial channels in which high pressure prevails, check valves are provided so that no high pressure fluid can flow from a high pressure outlet chamber into a cylinder chamber still filled with low pressure fluid.

摘要： In a hydostatic rotary pump or motor having a cylinder block with cylinders, pistons are mounted which are provided with slide shoes engaging an eccentric annular actuating guide means so that the pistons are reciprocated. Each piston has a spherical end face in sliding contact with a spherical inner slide shoe face having the same radius and center. Mechanical connecting means mount the slide shoe on the piston for angular movement about the center.

摘要： The inward pressure exerted by the cylinder rotor of a hydraulic radial piston machine on the stationary control member on which the rotor rotates, is compensated by balancing chambers on control portions between the high and low pressure ports of the control member. Fluid under high pressure is supplied from the high pressure port to the respective control portion on which the inward pressure of the cylinder of the piston in the inner radial dead center position acts. The conduit system of the control member includes check valves preventing communication between the high pressure port and the low pressure port.

摘要： The outlet pressure and pumped volume of a radial piston pump are automatically regulated by adjusting the eccentricity of the actuating ring which reciprocates the pistons during rotation of the cylinder block of the pump. A spring urges the actuating ring in one direction to a position in which the maximum volume is pumped, and a control valve, responsive to the pressure in the outlet conduit, opens at an excess pressure and supplies fluid to a regulating chamber between the actuator ring and a stator cavity, overcoming the spring force and reducing the eccentricity of the actuating ring and thereby the pressure and flow volume in the outlet conduit.

摘要： A hydraulic pump or motor of the radial piston type has a control ring for the pistons whose eccentricity to the axis of the rotor determines the transported volume of fluid. Two pistons are diametrically disposed in an axial plane and abut the control ring. The pistons are respectively connected with a source of fluid whose pressure is variable, and with the high pressure side of the hydraulic apparatus so as to vary the eccentricity of the control ring while the same is guided by two supporting means which are diametrically disposed in an axial plane perpendicular to the first-mentioned axial plane.
