Abstract: A pump for moving a fluid has a housing with a cylindrical internal chamber accommodating a cylindrical piston. The piston is eccentrically secured to a shaft rotatably mounted on the housing. A baffle located in a recess in the housing controls the flow of fluid through the housing from a fluid inlet passage to a fluid outlet passage. A pair of cams eccentrically mounted on the shaft linearly move cam followers connected to the baffle to maintain an end of the baffle in close relation to the piston as the piston turns in the chamber.

Abstract: The present invention relates to a rotary piston pump for conveying and/or metering liquid or pourable media. It consists of a pump casing (2) with a cylinder chamber (4) having a cylindrical inner periphery (6) into which open at least one inlet (8) and at least out outlet (10), and a rotary piston (20) rotating inside the cylinder chamber (4) which, together with at least one region of its outer peripheral surface (22) forms a seal with the inner peripheral surface (6) of the cylinder chamber (4) and is separated in regions from the inner peripheral surface (6) by a radial stroke distance. When the rotary piston rotates (arrow 70), an expanding working chamber (24) is formed in the region of the inlet (8) to draw the medium in and, on further rotation, contracts again in the region of the outlet to force the medium out.

Abstract: A rotary engine includes a stationary engine block and a power shaft mounted along a central axis for rotation with the engine block. An annular working chamber is formed in the engine about the central axis. A working member is connected to the power shaft to travel in a circular path about the central axis through the annular working chamber. The engine block has an elongated passage which extends through or across the annular working chamber in a direction perpendicular to the travel of the working member. An elongated bar is received within the elongated passage for slidable movement therethrough between first and second positions. The elongated bar includes a slot which is aligned with the annular working chamber when the elongated bar is in its first position to allow passage of the working member therethrough. The elongated bar forms a wall across the annular working chamber when the working member is in its second position to divide the annular working chamber into expansion and exhaust chambers.

Abstract: The eccentric wheel, which is driven to rotate in the housing of a compressor, having two eccentric axles longitudinally aligned at two opposite ends for mounting a pair of links to hold a blocking plate. The blocking plate is carried by the links to displace when it is constantly disposed in contact with the eccentric wheel, and therefore, friction between the blocking plate and the eccentric wheel is greatly improved.
