Abstract
A valve bushing having an actuator portion and a pin guiding component is disclosed. The actuator portion has a cup-shaped body with a stepped bore that defines a chamber in which a piston for opening and closing a valve gate disposed, and also defines a transfer bore extending through a base portion of the cup-shaped body. A stand-off member elevates the cup-shaped body from the manifold. The pin guiding component defines a sealing bore that extends between a body portion and a boss that extends rearward from the body portion. The boss is received in the transfer bore of the cup-shaped body to define a thermal transfer area between the pin guiding component and the actuator portion that is spaced apart from the manifold, and the actuator portion is located relative to the pin guiding component by engagement between the pin guiding component and the stand-off member.
