| 418243000 | POSITIVELY ACTUATED ABUTMENT | 7 |
| 20120156081 | Shaft Structure in a Pneumatic Actuator - An improved structure of a central shaft in a pneumatic actuator comprises an actuator having an actuator chamber; a vane which is hingedly located at a shaft hole of the actuator. The central shaft is cylindrical and short, and the short central shaft has a through hole which is a through octagonal opening symmetric to a center thereof. It can be easily processed and precisely aligned. The advantage of the short central shaft is that the actuator itself can connect to non-pressured sources such as an upper and lower central shafts, and connect to different inserting drivers to form a central shaft as a unit in the pneumatic actuator to directly connect to a central shaft of a valve or indirectly through a connecting bracket instead of using a conventional connecting coupler. The octagonal opening provides alignment positions at every 45 degrees for the upper and lower central shafts to increase diversities of usage. | 06-21-2012 |
| 20150071807 | SWINGING ABUTMENT ROTARY PUMP - A rotary pump device includes a stator chamber with a cylindrical inner wall having intake and exhaust ports and a swinging abutment mounted therein, and a rotor eccentrically mounted on an axial drive shaft for rotation within the chamber. The rotor keeps continuous wiping contact with the chamber wall while the swinging abutment maintains contact with the rotor to partition the intake and outlet ports. In a single abutment configuration, a full intake/exhaust cycle occurs every 360° of rotor travel. | 03-12-2015 |
| 20160201462 | Non-Coaxial Multi-Axial Rotating Mechanism | 07-14-2016 |
| 418244000 | Cam actuated | 2 |
| 20150322790 | ROTATION DEVICE AND ROTOR COMPRESSOR AND FLUID MOTOR HAVING THE SAME - A rotating device includes a cylinder body, a front end cover, a rear end cover, a main shaft, an eccentric rotor assembly and an isolation mechanism. The eccentric rotor assembly includes an eccentric shaft, a rolling piston wheel and at least one rolling bearing. In the rotating device, the eccentric shaft is isolated from the rolling piston wheel by the rolling bearing and the two are rotated, and the cylinder body is reliably sealed by an elastic pre-tightening force. Further provided are a rotor compressor using the rotating device, and a fluid motor. A rotating valve body and a rotating valve body reset mechanism in the rotating device are also improved. | 11-12-2015 |
| 418246000 | Spring or fluid biased in opposite direction | 1 |
| 20150125332 | PUMP - A pump having a stroke ring which has an axial recess, a rotor which is received in the axial recess so as to be rotatable relative to the stroke ring, wherein the rotor has radial recesses in which delivery elements are displaceable received as viewed in a radial direction, a side plate which closes off the axial recess on a first side, a pressure plate which closes off the axial recess on a second side, wherein the pressure plate has at least one opening, wherein a pressure region of the pump is fluidically connected to external surroundings of the pressure plate through the at least one opening, and wherein at least one fluid path is provided from the pressure region of the pup into an under-vane region of the delivery elements, and a cold-start plate which is preloaded against the pressure plate by means of a spring element such that, at least when the pump is at a stand-still, the cold-start plate closes the at least one opening in the pressure plate to the external surroundings of the pressure plate. The pump is characterized in that the spring element is supported on the pressure plate so as to introduce preload forces into the cold-start plate, and in that the spring element is fastened to the pressure plate. | 05-07-2015 |
| 418248000 | Spring biased | 1 |
| 20100310403 | OSCILLATING VARIABLE DISPLACEMENT RING PUMP - An oscillating variable displacement ring pump provides both positive and variable displacement. A housing circumscribes a pump chamber. The pump chamber encases an oscillating ring driven by a crank assembly. The ring encircles an end of the crank assembly. The crank assembly includes an annular spacer that rolls inside the ring. When the pump chamber is sealed, rotation of the crank assembly causes ring oscillation in the chamber. Ring oscillation creates vacuum pressure, which draws substances into pump chamber via an inlet port while pumping out substances of the pump chamber via an outlet port. A valve within the pump chamber contacts the ring and follows ring oscillation to help separate incoming substances from outgoing substances. The pump can include an adjustable internal by-pass means to control the volume and pressure of substances delivered by the pump. | 12-09-2010 |

| 20100092324 | Variable capacity rotary compressor - Provided is a variable capacity rotary compressor, which has a passage for restricting a vane using a pressure applied towards a perpendicular direction to a direction of a motion of the vane. A ratio between a sectional area of the passage and a vane area of the vane facing the passage and receiving a restriction pressure applied thereto ranges from 1.5% to 16.4%, and accordingly the vane can smoothly perform a reciprocation upon a normal driving mode of the compressor and also the vane can be quickly restricted upon a saving driving mode of the compressor. Hence, the fast and stable restriction of the vane can prevent a vibration of the vane, so as to reduce noise generated from the compressor. | 04-15-2010 |
