摘要： A bottom portion of an intake port is provided with a sloped bottom surface formed of a plane such that sloped bottom surface approaches the side surfaces of external teeth and internal teeth from an upstream side to a downstream side in rotational direction of two rotors. Fluid that flows in the intake port is regulated by the sloped bottom surface and smoothly guided into individual inter-teeth chambers that are expanding. Since the sloped bottom surface on the bottom portion of the intake port is formed of a plane without spiral or twisting, design and manufacturing of a gear pump is extremely easy.

摘要： Improved gerotor pumps comprising laterally constrained floating rings, thereby providing an orthogonal degree-of-freedom and allowing gerotor sets positioned therein to establish their own preferred mesh orientation, and additionally wherein the outer rotor of the gerotor set is forcibly positioned against the inner rotor of the gerotor set at the gerotor set's in-mesh position whereat there is little relative motion between the inner and outer rotors, thereby resulting in a substantially friction- and wear-free meshing action of the gerotor set.

摘要： A scroll compressor includes an adjustable actuator mount that changes the relative position of a non-orbiting scroll and an orbiting scroll to change the compressor capacity. In one embodiment, the scroll wrap and base of each scroll are manufactured as two separate components with a wrap modulator between the scroll wrap and the base of each scroll. As the mount moves the scrolls apart and together, the wrap modulators extend and retract the scroll wraps relative to their respective bases to maintain fluid-tight compression chambers.

摘要： A scroll type compressor has a housing, a fixed metal scroll member and a movable metal scroll member. The fixed and the movable scroll members each have a base plate and scroll wall extending therefrom. The fixed scroll member is fixed to the housing. The movable scroll member engages the fixed scroll member to trace an orbital motion when driven by a crank mechanism. The scroll members define compression chambers. Resin tip seals are respectively provided on distal ends of the scroll walls and slidably engage the metallic surfaces of the facing base plates. The tip seals seal the compression chambers. A resin coating layer is formed on a region of at least one of the end surfaces of the base plates that is not contacted by a tip seal.

摘要： An abrasion resistance structure of a scroll compressor is provided. In the abrasion resistance structure, including a main frame penetrated by a driving shaft combined with a rotor of a driving motor and supported in a radius direction, a fixed scroll fixed to the main frame, and an orbiting scroll put on the main frame, eccentric-combined with the driving shaft so as to be in an orbiting motion, and forming compression pockets together with the fixed scroll while continuously moving in a state of being geared with the fixed scroll, concavely inclined portions are formed on the back surface of an end plate of the orbiting scroll facing the upper surface of the main frame and on the upper surface of the main frame. Accordingly, it is possible to prevent abrasion between the orbiting scroll and the main frame due to the thermal deformation of the orbiting scroll during the operation of the compressor.
