  • Patent number: 6422531
    Abstract: A valve insert comprises a bushing assembly, a piston assembly and a spring. Its design prevents non-longitudinal movement of the piston assembly as it is moved within the longitudinal bore of the bushing assembly. This virtually eliminates the bell clapper effect commonly suffered by many of the valve inserts currently used in the industry. The design of the valve insert also avoids the pressure imbalances inherent to the prior art valve inserts. The valve insert is designed to fit snugly and sealingly within a suitable borehole, such as the fill and cut-out boreholes of an ECP manifold assembly.

  • Patent number: 6416034
    Abstract: A vent valve insert comprises a bushing assembly, a piston assembly and a spring. It is designed to fit snugly and sealingly within a suitable borehole, such as the vent borehole of an ECP manifold assembly. The bushing assembly defines a longitudinal bore within which the piston assembly is situated. When pilot pressure is applied to its top surface, the piston assembly is forced to an open position wherein fluid is allowed to flow through the vent valve insert. Absent pilot pressure acting against the top surface, the spring acts to force the piston assembly upward within the longitudinal bore. Secured to the bottom portion of the piston assembly, an annular sealing member is carried upward so that its flat surface seats against a raised inner portion of an annular valve seat. The vent valve insert is thus normally biased to the closed position.

  • Patent number: 6186411
    Abstract: A nozzle assembly allows a metered dose of lubricant to be dispensed. It comprises a housing and a piston assembly. The housing defines a piston bore, a stem bore and a spout, all of which axially aligned. It also defines a lubricant passage, an air inlet, and a channel linked to the inlet. Connectable to a source of lubricant, the passage communicates with the stem bore. Connectable to a source of air, the inlet communicates with the stem bore at a position between the passage and spout. The piston assembly has a piston with stem and a spring. The piston lies in the piston bore, its back communicating with the channel. The protrudent end of the stem protrudes into the stem bore and has a groove defined about its circumference. The spring biases the piston assembly into a charge position wherein the groove aligns with the passage. This enables the groove to fill with lubricant.
