摘要:
A rotary-vane internal combustion engine of the cat and mouse or scissor type with coordinated rotation of two co-axial shafts with position sensors creating chambers of variable volume for intake, compression, power and exhaust strokes. A reversible electric generator motor on at least one of the shafts with an electronic control system for current, an energy storage unit and electrical load. The total work done and angular speed is calculated or empirically determined while an alternating accelerating or decelerating torque is applied for a continuous, uniform rotation cycle.

A rotary machine with a deformable rhomb includes a rotor formed by a deformable rhomb in contact, with or without clearance, with an internal surface of a housing forming a stator and/or with an external surface of a central crown, the deformable rhomb including four pistons connected one following the other by a pivotal hinge with an axis parallel to a longitudinal axis of the housing and thus forming a closed chain; a transmission mechanism to transmit movement between the pistons and a rotation shaft coaxial to a central axis of the machine, the transmission mechanism including a first rolling body mounted fixedly on at least one piston, an axis of the first rolling body passing in the center of the piston and connected to a second rolling body, a center of which passing through the central axis of the machine and being integral with the rotation shaft, the first rolling body being connected to the second rolling body directly or by an intermediate transmission member, wherein a demultiplication ratio between the first and the second rolling body is equal to 2 and is positive.

A scroll compressor is disclosed that has a novel anti rotation means, which is incorporated directly into the wraps of the scrolls themselves, rather than comprising a separate mechanism. The scroll wraps are machined with integral, semi cylindrical troughs and ridges, which have centers lying on equally angularly spaced swing radius lines. The troughs and cylinders on the two scrolls are angularly offset relative to one another by one half of the equal angular increment that separates the swing radius lines on which the troughs and ridges lie. The difference between the radius of the larger troughs an smaller ridges is equal to the inherent orbital radius of the scrolls. This geometrical relationship allows the ridges to move along and through the troughs as the scrolls relatively orbit with, at any point in the cycle, at a pair of adjacent ridges engaged with opposing halves of adjacent troughs. Thus, the scrolls are always prevented from relatively rotating as they relatively orbit.
摘要:
A positive displacement apparatus including first and second scrolls having interfitting vanes defining at least one fluid receiving moving pocket movable between an inlet and an outlet. The scrolls are mounted on parallel but offset axes by shafts such that one scroll orbits relative to the other. One of the shafts is driven by a motor and the scrolls are interconnected by a flexible band located peripherally of the scrolls for synchronization purposes.
摘要:
A compact, rotary gas-operated motor having only two moving components, including valving. Pressurized gas causes an elongate rotor to rotate end-over-end within a generally triangular chamber and causes a crank to slide in a slot in the elongate rotor. A disk rotating with the shaft includes ports to admit pressurized gas and exhaust spent gas. The inlet port is shaped and positioned to provide early cut-off of inlet gas and provide up to 2:1 expansion ratio of the pressurized gas. Still earlier cut-off of inlet gas, at a location between the rotating disk and its housing, provides expansion ratios as high as 9:1. A movable guillotine may be used to provide continuously variable expansion ratios of from about 3:1 to 9:1.

A rotary internal combustion engine comprises a housing, a rotor mounted for eccentric rotation within the housing, a separator arrangement engaging the rotor for dividing, in cooperation with the rotor, the housing into at least two chambers. The housing is provided with a number of intake and exhaust ports. A valve member is secured to the rotor for rotation therewith and has a valve opening therein positioned for successive juxtaposition to the housing ports. Optional manifolding and valving arrangements are disclosed.

A pump device includes a shaft, a first gear pair, a second gear pair, a support pin, and a casing. The first gear pair includes a first driving gear which is disposed on the shaft and is rotatable together with the shaft, and a first driven gear driven by the first driving gear. The second gear pair includes a second driving gear which is disposed on the shaft coaxially with the first driving gear and is rotatable together with the shaft, and a second driven gear driven by the second driving gear and arranged coaxially with the first driven gear. The support pin penetrates the first driven gear and the second driven gear and rotatably supporting the first driven gear and the second driven gear. The casing covers the first gear pair and the second gear pair. The support pin is fitted to the casing to be fixed.
摘要:
A rotary piston pump equipped with a motor having two counter-rotating rotary pistons. The two rotary pistons are housed in an oval pump housing. The two rotary pistons are arranged on a first output shaft and a second output shaft. The first output shaft and the second output shaft are driven and synchronized via at least one elastic element.

A compressor drive shaft may include a first bearing portion, a second bearing portion, and an intermediate portion disposed therebetween. The intermediate portion may include a continuous, nonlinear, central axis in an unloaded state.
摘要:
A rotary machine operable as a pump, compressor, motor or internal combustion engine, the machine having a rotor orbiting but not rotating within a chamber in a housing, vanes separating the space within the chamber into working chambers. The rotor is eccentrically mounted on a rotatable shaft, the rotor being guided by lobes on the rotor operating in shaped recesses in the housing. The vanes are vane assemblies biassed outwardly into contact with the chamber wall, and include a plurality of vane blades to give a labyrinth seal effect.
