摘要： A valve cover assembly for a pump. In an embodiment, the valve cover assembly comprises a first cylindrical member having a central axis and a first throughbore. In addition, the valve cover assembly comprises a second cylindrical member coaxially disposed within the first throughbore and rotatable relative to the first cylindrical member about the central axis between a first position and a second position. In the first position, the second cylindrical member is axially translatable relative to the first cylindrical member. In the second position, the second cylindrical member is axially fixed relative to the first cylindrical member.

摘要： A liquid additive injection pump for injecting a predetermined amount of a secondary fluid into a primary fluid stream wherein a fluid mixing chamber is disposed within the pump housing assembly. A gasket having at least one one-way valve is positioned between the pump assembly components and mixing chamber thereby allowing a primary fluid to pass through the pump assembly and into the mixing chamber where the introduction of a second fluid occurs. The mixed fluids are then discharged through an outlet. The one-way valve gasket assembly acts to prevent the mixed and/or secondary fluid from passing upstream of the gasket assembly and into the pump assembly.
