Title:
PARALLEL-CONNECTED TYPE ELECTROMAGNETIC PUMP
Document Type and Number:
Japanese Patent JPS63186972
Kind Code:
A
Abstract:
PURPOSE: To increase the pump capacity by fitting two drive mechanisms reciprocating pistons in cylinders to a main body, forming passages passing intake valves and discharge valves in parallel respectively, and providing an intake port and a discharge port on the main body.
CONSTITUTION: Two drive mechanisms 1a, 1b are fitted to the upper section of a main body 2, and pumps are driven by an electromagnetic coil 12. Thereby, intake valves 44a, 44b and discharge valves 51a, 51b are operated together to perform the pump action, a fluid is sucked through an intake port 40 and discharged to the outside through a discharge port. Since two pumps are provided in parallel, the pump capacity can be increased without expanding the piston diameter.
