HYDROSTATIC RADIAL PISTON UNIT - A simplified explanation of the abstract

This abstract first appeared for US patent application 20240044319 titled 'HYDROSTATIC RADIAL PISTON UNIT

Simplified Explanation

The abstract describes a hydrostatic radial piston unit of the cam-lobe type, which includes a shaft defining a rotational axis. The unit consists of a non-rotary, stationary rear casing connected to a front casing via a front end region of the shaft. Within the front casing, a cylinder block is fixed to the front end region of the shaft. The cylinder block contains radially reciprocating working pistons in radially oriented cylinder bores, which can be supplied with hydraulic fluid through a distributor. The distributor is rotationally fixed to the front casing and rotationally free relative to the shaft. The front casing has a circumferential cam-lobe surface that interacts with the working pistons.

• The patent describes a hydrostatic radial piston unit of the cam-lobe type.
• The unit includes a shaft with a rotational axis and a non-rotary rear casing.
• A front casing is connected to the rear casing via the front end region of the shaft.
• A cylinder block is fixed to the front end region of the shaft and contains working pistons in radially oriented cylinder bores.
• Hydraulic fluid can be supplied to the cylinder bores through a distributor.
• The distributor is rotationally fixed to the front casing and rotationally free relative to the shaft.
• The front casing has a cam-lobe surface that interacts with the working pistons.

Potential Applications:

• This technology can be used in various hydraulic systems that require radial piston units, such as industrial machinery, construction equipment, and automotive applications.
• It can be applied in hydraulic pumps, motors, and actuators that require precise and efficient radial piston movement.

Problems Solved:

• The hydrostatic radial piston unit provides a compact and efficient design for converting hydraulic energy into mechanical motion.
• The cam-lobe type construction ensures smooth and controlled reciprocating movement of the working pistons.
• The torque-proof connection between the cylinder block and the shaft prevents any rotational slippage, ensuring accurate piston movement.

Benefits:

• The hydrostatic radial piston unit offers high power density and efficiency, making it suitable for demanding applications.
• The cam-lobe design provides precise control over the piston movement, resulting in improved performance and reduced wear.
• The compact design allows for easy integration into existing hydraulic systems, reducing installation and maintenance efforts.

Original Abstract Submitted

a hydrostatic radial piston unit of the cam-lobe type of construction including a shaft defining a rotational axis of the hydrostatic radial piston unit. the shaft extends with a front end region from a non-rotary, stationary rear casing to a front casing. within the front casing a cylinder block is housed and fixed in a torque-proof connection to the front end region of the shaft. in the cylinder block radially reciprocating working pistons are disposed in radially oriented cylinder bores to and from which cylinder bores hydraulic fluid can be conducted by means of a distributor. the distributor is arranged rotationally fixed with respect to the front casing and rotationally free relative to the shaft. a circumferential cam-lobe surface with which the working pistons can interact, is formed integrally with the front casing on its radial inner side.
