Abstract
An improved sealing means for use with a slide gate which is slidably mounted for opening and closing movement relative to a seat forming frame defining a fluid flow orifice. The sealing means comprises a resilient sealing member adapted to be received in a groove in the frame, the groove having an outer compartment in which the body of the sealing member is sealed and an inner compartment underlying the outer compartment, the sealing member having an outwardly projecting contoured face adapted to be contacted and displaced laterally inwardly by the gate as it is closed, the lateral displacement of the face of the sealing member causing a rear portion of its body to be displaced into the inner compartment of the groove, thereby accommodating the sealing member to the slide and relieving forces acting to shear the sealing member.
