Reciprocating diaphragm pump with degassing valves
First Claim
1. A reciprocating pump for delivering fluid comprising:
- a diaphragm that is reciprocated so as to deliver fluid;
a diaphragm drive chamber provided therein with said diaphragm;
a drive-power supply member for supplying drive power for reciprocating said diaphragm;
wherein drive power of said drive-power supply member is transmitted to said diaphragm within said diaphragm chamber via operating fluid and an operating-fluid-flow regulation chamber for regulating the flow of operating fluid is located between said drive-power supply member and said diaphragm drive chamber;
a first gas discharge member and a second gas discharge member are respectively located in an upper part of the inside of said operating-fluid-flow regulation chamber and an upper part of the inside of said diaphragm drive chamber;
said first gas discharge member is held in fluid communication with said second gas discharge member so as to constitute a single gas discharge mechanism, said single gas discharge mechanism being provided with a reverse-flow prevention member for preventing a reverse flow of fluid from said first gas discharge member to said second gas discharge member;
said single gas discharge mechanism is made up by using said first gas discharge member, said second gas discharge member, said reverse-flow prevention member and a fluid-discharge adjusting member; and
said fluid-discharge-adjusting member is made up by using a ball member provided above said reverse-flow prevention member, and an adjustment valve for adjusting a lift amount of said ball member.

Abstract
In a reciprocating pump, drive power of a drive-power supply member is transmitted to a diaphragm within a diaphragm drive chamber via operating fluid. An operating-fluid-flow regulation chamber for regulating the flow of operating fluid is located between the drive-power supply member and the diaphragm drive chamber. A first gas discharge member and a second gas discharge member are respectively located in an upper part of the inside of the operating-fluid-flow regulation chamber and an upper part of the inside of the diaphragm drive chamber. The first gas discharge member is held in fluid communication with the second gas discharge member so as to constitute a single gas discharge mechanism. This single gas discharge mechanism is provided with a reverse-flow prevention member for preventing a reverse flow of fluid from the first gas discharge member to the second gas discharge member.

5. A reciprocating pump for delivering fluid comprising:
-
a diaphragm that is reciprocated so as to deliver fluid;
a diaphragm drive chamber provided therein with said diaphragm;
a drive-power supply member for supplying drive power for reciprocating said diaphragm;
whereindrive power of said drive-power supply member is transmitted to said diaphragm within said diaphragm drive chamber via operating fluid, and an operating-fluid-flow regulation chamber for regulating the flow of operating fluid is located between said drive-power supply member and said diaphragm drive chamber;
said operating-fluid-flow regulation chamber is provided with a valve element that is provided adjacent to said diaphragm to be driven along with said diaphragm, and a valve seat that is brought into engagement with said valve element so as to regulate operating fluid supplied into said diaphragm drive chamber;
a first gas discharge passage and a second gas discharge passage are respectively located above said operating-fluid-flow regulation chamber and above said diaphragm drive chamber;
said first gas discharge passage is held in fluid communication with said second gas discharge passage so as to constitute a single gas discharge mechanism, said first gas discharge passage having a first end in fluid communication with said operating-fluid-flow regulation chamber via an upper part of the inside thereof between said drive-power supply member and said valve seat;
said second gas discharge passage having a first end in fluid communication with said diaphragm drive chamber via an upper part of the inside thereof between said valve seat and said diaphragm; and
said single gas discharge mechanism is provided with a first ball member that rests on a second end of said first gas discharge passage so as to prevent operating fluid from reversely flowing from said second gas discharge passage into said first gas discharge passage, and a second ball member that rests on a second end of said second gas discharge passage so as to prevent operating fluid from reversely flowing from said first gas discharge passage into said second gas discharge passage. - View Dependent Claims (6, 7)
