摘要： One example of a gerotor pump includes an inner rotor comprising multiple teeth, the inner rotor configured to rotate about a first longitudinal gerotor pump axis. The gerotor pump also includes a hollow outer rotor including an outer surface and an inner surface having substantially identical contours, the inner surface configured to engage with the multiple teeth and to rotate about a second longitudinal gerotor pump axis. The pump includes a pump housing within which the inner rotor and the outer rotor are disposed, wherein the outer surface of the outer rotor defines gaps between the pump housing and the outer rotor.

摘要： 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.

摘要： A scroll compressor includes a compression mechanism having fixed and movable scrolls defining a compression chamber, an introduction mechanism, and an auxiliary introduction mechanism. The introduction mechanism supplies fluid from the compression chamber to a back-pressure chamber supply throughout a first period. The auxiliary introduction mechanism has an auxiliary introduction passage and a check valve. The auxiliary introduction mechanism supplies fluid from the compression chamber to a back-pressure chamber supply throughout a second period. The second period includes a time point prior to the first period.

摘要： A pressure control valve (100, 200) comprises a valve seat (140, 160) in which is formed a valve hole (142, 162), a first valve sheet member (110, 210) which covers the valve hole and is provided with a fluid passage (118, 218) thereon, and a second valve sheet member (120, 220) which is provided between the valve seat and the first valve sheet member and covers the fluid passage. Wherein, given that the direction directed from the second valve sheet member to the first valve sheet member is a first direction, when the pressure difference across two sides of the first valve sheet member and the second valve sheet member is directed to the first direction and is greater than or equal to a first preset value, the first valve sheet member is opened; when the pressure difference is directed to a second direction opposite to the first direction and is greater than or equal to a second preset value, the second valve sheet member is opened. Also disclosed is a scroll compressor comprising the pressure control valve. Also disclosed is a scroll compressor comprising a throttle valve for preventing or weakening the return flow from the back-pressure chamber to the pressure chamber.
