    摘要: The present document describes a rotating and reciprocating piston device comprising: chambers disposed about a chamber axis, the chambers having two ends and a port for passage of a fluid at each one of the ends of the chambers; pistons having two ends, each one of the pistons slidably positioned within a respective one of the chambers thereby determining a space at either end of each piston within its respective chamber; and a track forming a closed circuit through which the chamber axis passes, the track for determining a position of a piston within its respective chamber and hence the space on either side thereof.

    摘要: A Positive Fluid Displacement Device (PFDD) with a removable Fluid Displacement Module (FDM) having two opposing pistons connected to a drive block. The drive block slides over a crankpin bearing in assembly to provide orbital piston motion. Opposing cylinders are held within a carriage for reciprocating motion. An opening in the reciprocating cylinder head allows fluid communication to the displacement chamber through inlet and outlet ports in a floating port plate. The flat surfaces of the port plate and cylinder head wipe across each other during cylinder head movement. The piston head carries a protrusion sized to fill the cylinder head opening. Micro-adjustment mechanisms for the position of the cylinder head together with compliant piston and compliant cylinder mechanisms can provide near zero dead volume. Different sized opposing cylinders enable the delivery of pumped fluids in precise ratios. By connecting the outlet of each cylinder to the inlet of the opposing cylinder, the differential displacement of the two cylinders can be pumped, enabling the delivery of very small quantities of fluid. High vacuum may be delivered by series connection of cylinders. The device may incorporate a dual lip piston seal which is wear compensated over the life of the seal. The PFDD is leakage free and can be driven by stepper motors to deliver a precise fluid amount at low speed even to an exact portion of a piston stroke. A sensor is provided for sensing cylinder head position.

    摘要: An air discharging apparatus to discharge pressurized air at a predetermined timing is disclosed. The disclosed air discharging apparatus includes an air pump including a cylinder and a piston configured to reciprocate in the cylinder; an opening and closing member provided at an air discharge opening of the air pump and configured to open and close the air discharge opening; and a switching mechanism providing mechanical coupling between the piston and the opening and closing member. The mechanical coupling keeps the opening and closing member in a closed state until the piston reaches a predetermined position in a compression stroke and switches the opening and closing member to an opened state when the piston reaches the predetermined position.
