Pump

Abstract

A diaphragm type pump for feeding a low viscosity fluid such as air under high pressure while minimizing the size of a feeding means. The pump connected with a feeding pipe and a delivery pipe and delivering fluid fed from the feeding pipe from the delivery pipe, comprises a housing provided with a storage chamber communicating with the feeding pipe and the delivery pipe through a one-way valve, respectively, and storing the fluid temporarily, a diaphragm arranged oppositely to the storage chamber and driven to advance or retract thus sucking the fluid from the feeding pipe into the storage chamber and then pushing out the fluid to the delivery pipe, and a section for driving the diaphragm to advance or retract. The diaphragm is provided with a ring-like tube along the outer circumferential edge thereof, and the diaphragm is fixed to the housing through the tube thus advancing or retracting the diaphragm while deforming the tube elastically.

Description

technical field

[0001] The present invention relates to a diaphragm type pump that feeds a fluid by driving a plate-shaped vibrating plate forward and backward instead of a diaphragm of a diaphragm pump. Background technique

[0002] Conventionally, a diaphragm pump is generally used as a driving source for fluid feeding. This type of diaphragm pump is provided with a storage chamber for temporarily storing a fluid in a casing constituting the outer frame of the diaphragm pump, and a diaphragm is arranged facing the storage chamber. At the same time, the storage chamber is connected with the feeding pipe and the sending pipe respectively through the one-way valve.

[0003] Through the elastic deformation of the diaphragm and the backward state relative to the storage chamber, the pressure in the storage chamber can be reduced, thereby attracting the fluid from the feed pipe into the storage chamber; through the elastic deformation of the diaphragm relative to the storage ch...
