Abstract
PURPOSE: To improve sealing performance by providing a sealing member which at one end has a fitting section connected with an opening of a pump case, at the other end a sealing section airtightly fixed to a pumping tube and in the middle an inflexible section, thereby for higher pumping efficiency.
CONSTITUTION: Each sealing member 15 for sealing a gap between a pumping tube 5 and an opening 2 of a pump case 1 is made up by one single vacant cylindrical body. The sealing member 15 consists of a fitting section 16 at one end, connected with an opening 2 of the pump case 1, a sealing section 17 at the other end, airtightly fixed to the periphery of the pumping tube 5 and an inflexible section 18 in the middle, thicker than the sealing section 17. The inflexible section 18 is prevented from sliding fro and rear on the pumping tube 5 and greatly expanding under a negative pressure in the pump case 1. Keeping a constant negative pressure in the pump case 1 may improve pumping efficiency.
