A valve flow-directing vessel () comprising a sleeve () having a threaded installation portion () for connection to a receiving member, a plunger () movable within the sleeve () between a closed position and an opened position, and an orifice insert () fixedly attached to the sleeve (). The orifice insert () defines an orifice () that is sealed when the plunger () is in the closed position and unsealed when the plunger () is in the opened position. The orifice () is the entrance to a passageway () having an exit () communicating with a delivery passage of the receiving member, and this exit () is positioned beyond the threaded installation portion () of the sleeve ().

Solenoid valve

An improved solenoid valve assembly for controlling fluid flow having a valve body with an inlet and outlet, a diaphragm assembly with passages for providing fluid communication between the inlet and the outlet, and a movable seal pad responsive to an external signal for controlling flow through one of the passages. The improvement has the diaphragm assembly including a symmetrical fluid flow restrictor movable within the valve body, with a head portion, an intermediate portion and a guide portion surrounding a main body portion. The head portion has a fist end of the pilot passage which extends through the main body portion. The intermediate portion includes an annular extension with an upper side and a lower side. The guide portion has a plurality of legs extending from the main body portion for a distance substantially equal to the outer diameter of the annular extension, and is spaced from and interconnected with the intermediate portion by reduced diameter gullet portion.

Hollow piston restrictor

A valve is provided with an orifice member that is forcibly inserted into an opening of the valve body and the opening in the valve body is provided with a plurality of protrusions, or ribs, which are shaped and sized to deform in a particular manner during the insertion of the orifice member. The protrusions, or ribs, extend radially inward from the inner cylindrical surface of the opening in the valve body. The deformation of the ribs during the insertion of the orifice member provides sealing at the interface between the orifice member and the valve body and, in addition, rigidly holds the orifice member at a predefined position relative to the valve body and permits this position to accurately determined by using a datum surface during the assembly process.
