Полезная модель относится к области роторных двигателей внутреннего сгорания, к их вращающимся или качающимся рабочим органам, а именно к лопастям, шарнирно соединенным с внутренним и внешним элементами. Техническим является повышение герметичности рабочих камер двигателя.

A pneumatic motor includes a cylinder and a rotor disposed in the cylinder. The rotor includes an axle, and main and secondary blades are slidably received in a plurality of main and secondary sliding slots formed on the axle. The secondary blades touch an inner wall of the cylinder to promote torque output when located at angles equal to or smaller than a specific angle from an inlet of the cylinder. On the contrary, the secondary blades are away from the inner wall of the cylinder to reduce friction between the rotor and the cylinder when located at angles larger than the specific angle from the inlet. Thus, revolution speed of the rotor is retained in a tolerant range, and torque output is promoted significantly.

HYBRID ELASTOMER/METAL ON METAL MOTOR

A hybrid elastomer/metal on metal motor for a helical gear device includes a rotor and stator comprising a hydraulic motor that produces work when a working fluid is pumped therethrough. The improvement involves the stator being, for part of its length, a conventional or even wall stator, using an elastomer to form a seal against the moving rotor. The stator's remaining length comprises a profiled rigid surface that forms a seal directly with the moving rotor. This gives the motor the high efficiency of the elastomer sealing against the rotor, and simultaneously provides a backup of the stator's rigid section allowing continued motor operation at reduced efficiency, if the elastomer part failed in service. The invention also includes combinations of a regular disk stack with a rubber lining, a rigid material disk stack (or unitized element) and a circular rigid sleeve which react to rotor sideloading while permitting proper rotor orbiting. 1.

Tangential Force Internal Combustion Engine

Номер: US20190211678A1
Автор: McLean Hugh Bernard
Принадлежит:

A tangential force internal combustion engine invention utilizes the four cycle internal combustion engine process. Working gas chambers are formed via a torroid in the housing and two adjacent piston assemblies. Pistons, ring seals, and inner seal plate elements seal this chamber. The four gas cycles are spaced over the 360 degree torroid chamber with gas ports appropriately placed. One power vane (PV) and one reaction vane (RV) connect to a central shaft with pistons attached to each vane end. The PV produces driving torque on a central shaft through an Overrunning Clutch System (OCS). At specific angles and for controlled durations the PV and VN are slowed, stopped, held to the housing, and then accelerated and coupled to the shaft. Vane movement is controlled by gears, cam ramps, and pin mechanisms operating via three independent but time-coordinated systems. The power vane has no controlled acceleration; combustion pressure serves to immediately couple this vane to the shaft via the OCS. This immediateness and direct-coupling are thought to provide efficiency. 1. an internal combustion engine is which relies on two types of vanes , each of which has cyclic movement incorporating holds such that four Otto cycles can occur within a moving chamber formed by the ends of two adjacent pistons at the vane ends and located in a torroid chamber enclosed via multiple seals.2. a method of moving an engine vane directly with a shaft by locking an overrunning clutch roller element via ramps that push a pin through a hole in said vane thus inserting a finger end into the clearance side of the roller element cavity.3. a vane slot , gears , pin assemblies , and ramps such that a pin is pushed across a timing gear and into a vane slot via a fixed ramped cam in the housing thus initiating or halting movement of said vane upon 90 degrees of timing gear rotation.4. a method of holding vanes to the housing via a circumferential end face ramp in a timing gear such that a pin is ...

A system and method are presented for improved performance of gerotor compressors and expanders. Certain aspects of the disclosure reduce porting losses in a gerotor system. Other aspects of the disclosure provide for reduced deflection in lobes of an outer rotor of a gerotor system. Still other aspects of the disclosure provide for reduced leakage through tight gaps between components of a gerotor system. 1. A gerotor system comprising an inner rotor , an outer rotor having a plurality of ports , and a housing , the plurality of ports comprising an inlet subset of ports and an outlet subset of ports , wherein fluid flows into the gerotor system through the inlet subset of ports and out of the gerotor system through the outlet subset of ports ,the housing further comprising an inlet duct fluidly coupled with the inlet subset of ports and an outlet duct fluidly coupled with the outlet subset of ports, the inlet duct comprising an input pipe and the outlet duct comprising an outlet pipe, andwherein the inlet pipe is located on the inlet duct based upon a location of an inlet port in the inlet subset of ports having a highest inlet fluid velocity through the inlet port and the outlet pipe is located on the outlet duct based upon a location of an outlet port in the outlet subset of ports having a highest outlet fluid velocity through the outlet port.2. The gerotor system of claim 1 , wherein one of (a) an axis of the inlet pipe is aligned with a dominant fluid velocity vector through one or more of the inlet ports claim 1 , and (b) an axis of the outlet pipe is aligned with a dominant fluid velocity vector through one or more of the outlet ports.3. The gerotor system of claim 1 , wherein one of (a) a profile of one or more regions of the inlet duct is varied based upon the fluid velocity through one or more corresponding inlet ports claim 1 , and (b) a profile of one or more regions of the outlet duct is varied based upon the fluid velocity through one or more ...

An insert component for a scroll compressor comprises a polymer and at least one reinforcing or lubricating particle. The insert component comprises an annular body and an axial projection. The annular body defines a first centrally-disposed opening having has a central axis extending therethrough. The annular body has a first side comprising a first contact surface configured to engage a partition plate and a second side a second contact surface configured to engage a floating seal assembly. The first contact surface defines a slope between first and second radial locations. The axial projection extends from the annular body and can be received in a second centrally-disposed opening of the partition plate. The insert component can fluidly seal both a first interface between the first contact surface and the partition plate and a second interface between the second contact surface and a floating seal assembly during operation of the scroll compressor. 1.
