Radial piston rotary machine

Abstract

A radial piston rotary machine includes a housing, at least one opening for inlet of a medium to the machine and at least one opening for outlet of the medium from the machine, where the housing includes end caps between which a rotor is rotatably mounted. The rotor is composed of at least two plates, where a chamber for a reciprocating piston is provided in the rotor plate. The rotor plates are separated by a partition plate with an opening for a shaft of the machine. The shaft is mounted in rotary bearings in the end caps of the housing and circular cams are arranged on the shaft. The shaft is mounted eccentrically to the rotor, where the eccentricity of the axis of rotation of the shaft from the axis of the rotor is equal to the eccentricity of the axis of the circular cam from the axis of rotation of the shaft. Each piston is placed movably in reciprocation motion in the chamber for the piston in the rotor plate and rotatably on the circular cam on the shaft. The inlet and outlet of the medium to and from the piston chamber are opened and closed by valve means. The chamber for the piston is formed as a hole in the rotor plate, where at least two opposite walls of the hole are parallel for sliding arrangement of the piston. The piston is closed axially in the chamber at one side by the partition plate of the rotor plates and at the other side by an end plate of the rotor. The end plate comprises-includes an opening for the shaft and apertures for the inlet and outlet of the medium to and from the chamber. The apertures lead in the axial direction to the end cap of the housing, and are opened and closed by valve means in the form of separate arcuate slots.

1 . A radial piston rotary machine comprising a housing, at least one opening for inlet of a medium to the machine and at least one opening for outlet of the medium from the machine, where the housing comprises end caps between which a rotor is rotatably mounted, this rotor is composed of at least two plates, where a chamber for a reciprocating piston is provided in the rotor plate, and the rotor plates are separated by a partition plate with an opening for a shaft of the machine, the shaft being mounted in rotary bearings in the end caps of the housing, circular cams are arranged on the shaft, the shaft is mounted eccentrically to the rotor, where the eccentricity of the axis of rotation of the shaft from the axis of the rotor is equal to the eccentricity of the axis of the circular cam from the axis of rotation of the shaft, each piston is placed movably in reciprocation motion in the chamber for the piston in the rotor plate and rotatably on the circular cam on the shaft, where the inlet and outlet of the medium to and from the piston chamber are opened and closed by valve means characterized in that the chamber for the piston is formed as a hole in the rotor plate, where at least two opposite walls of the hole are parallel for sliding arrangement of the piston, which has at least two parallel opposing sides corresponding to two parallel opposing walls of the hole in the rotor plate, where the piston is closed axially in the chamber at one side by the partition plate of the rotor plates and at the other side by an end plate of the rotor, where the end plate comprises an opening for the shaft and apertures for the inlet and outlet of the medium to and from the piston chamber located by the walls of the hole in the plate forming the chamber that are against free ends of the piston, where the apertures lead in the axial direction to the end cap of the housing, and are opened and closed by valve means in the form of separate arcuate slots.
