Abstract: A fluid pump includes a pump body enclosing a first cavity and a second cavity, a first flexible member disposed within the first cavity, a second flexible member disposed within the second cavity, and a drive shaft extending between and attached to each of the first flexible member and the second flexible member. The drive shaft is configured to slide back and forth within the pump body. The pump also includes a first shift valve and a second shift valve disposed between the first flexible member and the second flexible member, operatively coupled to deliver a drive fluid to drive fluid chambers in alternating sequence. Some fluid pumps include a housing defining a modular-receiving cavity and a modular insert secured within the modular-receiving cavity by an interference fit. Methods of manufacturing and using fluid pumps are also disclosed.

Abstract: A pneumatic reciprocating fluid pump for pumping a fluid at least one check valve assembly that includes a check valve body insert, a ball within the valve body insert, and an annular sealing ring member disposed within a seat ring receptacle. The sealing ring member has dimensions smaller than corresponding dimensions of the seat ring receptacle, such that the sealing ring member is capable of moving within the seat ring receptacle. The ball is configured to slide back and forth between a first position and a second position within the check valve body insert responsive to forward and reverse flow of fluid therethrough. In one position, the ball is seated against the sealing ring member and prevents reverse flow of the fluid through the check valve assembly, and forward flow of the fluid through the check valve assembly is enabled when the ball is in another position.

Abstract translation: 一种用于泵送流体的气动往复流体泵，至少一个止回阀组件包括止回阀体插入件，阀体插入件内的球体和设置在座圈容座内的环形密封环构件。 密封环构件具有小于座圈容座的相应尺寸的尺寸，使得密封环构件能够在座圈容座内移动。 该球被构造成响应于流体的正向和反向流动而在止回阀体插入件内的第一位置和第二位置之间来回滑动。 在一个位置，球抵靠密封环构件就座，并防止流体通过止回阀组件的反向流动，并且当球处于另一位置时能够使流体通过止回阀组件的向前流动。
