Abstract:
A pump includes a base, a rotor, a slider block, a cover, and a drive member. Thus, the pump is used to pump the fluid in two opposite directions by changing the rotation direction of the rotor without having to change the parts of the pump, thereby enhancing the versatility of the pump, and thereby facilitating a user operating the pump. In addition, the pump has a simple apparatus with a lighter weight and smaller volume, thereby decreasing the space of operation and storage.
Abstract:
A cruciform pump comprises a casing, a positioning round disk in the casing; a driven rotary disk; and two sliding blocks. A center of the positioning round disk is arranged corresponding to a center of the casing, and has a cruciform sliding groove. The driven rotary disk is eccentrically installed on the positioning round disk. One rotary shaft at one surface of the rotary disk protrudes out of the casing. The two sliding blocks are installed in the cruciform sliding groove. Each block is conformed to the sliding groove, so that the positioning round disk is driven by the sliding blocks. When the driven rotary disk rotates through two circles, the positioning round disk only rotates through one circle. During rotation, the two sliding blocks move along the cruciform sliding groove; then, one side of the sliding block presses fluid flowing out, and another side thereof will suck fluid into the sliding groove.
Abstract:
A liquid pump comprises generally a base, an annular ring including a pair of ingresses and a pair of egresses alternately formed on opposing circumferential walls aside a pair of rectangular recesses therebetween and defining a fluid channel between the base and itself, first and second swivel disks including a rotary plunger and a pushing rod on their under sides and rotating inversely inside the pump. An elongate slider sliding to and fro in a rectangular groove coactes with the rotary plunger for repeatedly changing the vacuum circumstances in the channel to synchronously suck and discharge the liquid material from one container to another.
Abstract:
A blade-type fluid transmission device includes a rotor eccentrically located in the room of a stator and the outer periphery of the rotor is tangent to the inner periphery of the room. At least one blade is pivotably connected to stator and movably inserted in at least one slot of the rotor. The distal end of the at least one blade is in contact with the inner periphery of the room so as to form a space for receiving fluid between the outer periphery of the rotor and the inner periphery of the room. The contact between the at least one blade and the inner periphery of the room increases the efficiency for transmitting fluid which enters into the stator from an inlet and leaves from the stator from an outlet.
Abstract:
A fluid transport device for compressing or pumping a work fluid comprises a rotating coupling having an off-center first gear, a fixed internal second gear of twice the pitch diameter of the first gear, and a housing having a diametrical channel with a sliding piston disposed therein. A crank-like connector rotatably coupled with the first gear has a depending lug engaged within a hole in the piston and acts to drive the piston to and fro within the channel. First and second chambers are defined to either side of the piston, with the terminal ends of the chambers defined by the wall of the housing each having an egress aperture and an ingress chamber. A slotted depending rim of the coupling alternately obturates the egress aperture of one chamber and the ingress aperture of the other in step with the intake and expulsion stroke of the piston in each chamber.
Abstract:
A rotary fluid transmission device contains: a rotor, a drive shaft, a first holder, and a second holder. The first holder includes a circular bush and an annular chamber. The rotor includes a C-shaped piston which has an external face and an internal face. In addition, the annular chamber has a first reservoir defined between the internal face and the circular bush, and the annular chamber has a second reservoir defined between the external face and the inner fringe. The circular seat includes two clamp arms, and a respective clamp arm is rotatably engaged with a blade. The blade includes two abutting faces, and the C-shaped piston has two edge faces. The first holder includes two first conduits and two second conduits, the two first conduits are in communication with the first reservoir, and the two second conduits are in communication with the second reservoir.
