3results about "Engines with rotating cylinders" patented technology

A pump (100) includes: a cylinder block (30) configured to rotate together with a shaft (20); a piston (36) that is slidably inserted into a cylinder (31) formed in the cylinder block (30); a port block (50) having a first port (41) through which a working fluid supplied to a capacity chamber (32) flows and a second port (45) through which a working fluid discharged from the capacity chamber (32) flows; a cam ring (60) having a cam surface (61); and a capacity changing unit (70) configured to change an amount of the working fluid guided into the capacity chamber (32) by causing the port block (50) to rotate about a rotation center axis (C1) and changing a relative positional relation between the port block (50) and the cam ring (60).

A hydrostatic rotary machine with radial pistons comprising: an internal element and an external element coaxial and mounted to rotate relative to each other about an axis of rotation, one of these elements being a rotor and the other a stator; the internal element comprising a cylinder block (10); the external element comprising a cam track. The machine includes a drainage circuit which includes, for at least one cylinder (11), an injection conduit (26) passing through the wall of the cylinder (11), the injection conduit (26) opening at one end into the cylinder (11) through a port (27), and opening at the other end, from the cylinder block (10), into a drainage space supplied with hydraulic fluid.

The internal combustion engine comprises a first rotor member (11) rotatably carried according to a first axis of rotation (21) and a second rotor member (12) rotatably carried according to a second axis of rotation (22) coaxial with said first axis of rotation (21 ). A first and a second pair of opposed cylinders (30) are associated with said first rotor member (11). Said opposed cylinders (30) have respective pistons (31) adapted to define within the same cylinders (30) relative combustion chambers (32) and connected, by means of connecting rod means (33), to said second rotor member (12).
