PISTON PUMP |
摘要 |
<p>An efficient piston pump having a small number of parts and a simple assembly step, consuming less current in achieving a relatively low ultimate pressure. It is characterized by comprising an air suction port (28) through which a gas sucked by varying the volume of a pump chamber (22) defined by a cylinder (12) and a piston (14) fitted in the cylinder (12) passes as the piston (14) is reciprocated, an exhaust port (20) through which the gas to be discharged by varying the volume of the pump chamber (22) passes, an air suction valve (26) installed in the air suction port (28) disposed on the piston top, and an exhaust valve (18) installed in the exhaust port (20) disposed on the top of the cylinder (12).</p> |
