High volume positive displacement pump with gear driven rotary valves |
摘要 |
A positive displacement pump for gases includes a pair of pistons operating out of phase. Each of the pistons is associated with a plurality of rotary inlet valves disposed along the sidewalls of the piston cylinders. A rotary outlet valve is also associated with each piston and includes a rotating valve body disposed transversely across the cylinder head and which rotates in synchronism to open a through, radial port in the member in timed relationship to the piston travel. The positive displacement pump finds particular application heating, cooling and ventilating applications.
