摘要:
A rotary compressor or expander include a cylindrical housing chamber, a rotatable cylindrical rotor mounted eccentrically with respect to housing chamber centre, a cylindrical rotor liner free to move around the rotor, and a pivoting generally circular arc vane hinged to the rotor liner. Cavity or buckets engraved to the outer surface of the rotor liner together with corresponding inlet nozzle flow provide additional momentum impulse transfer from working fluid to expander eccentric rotor. The inlet of the rotary expander is equipped with a rotating valve synchronous to the eccentric rotor, regulating the admission time and duration of the entering working fluid. The exhaust of the rotary compressor is equipped with either a check valve or a rotating valve synchronising the fluid discharge time and duration.
摘要:
Rotary machine of the deformable rhombus type comprising a. a rotor (3) which is a deformable rhombus (4) in contact with the inner surface of an enclosure (1) forming a stator (2), said deformable rhombus (4) comprising four pistons (6) connected, in mutual succession, by a pivoting articulation (7) and thus forming a closed chain; and b. a transmission mechanism (14) for transmitting the movement between the pistons (6) and a rotary shaft (15) coaxial to the central axis of the machine, characterized in that said transmission mechanism (14) comprises: a first bearing body (16) mounted fixedly on at least one piston (6), preferably on each piston (6), the axis of said first bearing body (16) passing at the centre of the piston (6) and connected to a second bearing body (19) of which the centre passes through the central axis of the machine and is secured to said rotary shaft (15), the first bearing body (16) being connected to the second bearing body (19) directly or via an intermediate transmission member (18) - and in that the reduction ratio of the first (16) to the second bearing body (19) is equal to 2 and is positive.
摘要:
A rotary expanding or compressing mechanism provided in a fluid channel with blades for traversing a shaft comprises a supporting frame (1), an import (2) and export (3) of the fluid channel, a unround type curve barrel stator(4), a rotor (5) with concave grooves, blades (6) for traversing a shaft, a round end cap(7) and a member (8) for transmitting force. Wherein, a movable wearable sealing member (9,10,11) is provided in the matching position between the blade(6) and the stator (4). The mechanism is of good wearlessness and energy efficiency.
