Abstract: An injection pressure sensor (10) intended for use with a fluid source (12). The injection pressure sensor (10) has a sensor element (14) in communication with the fluid source (12) and in communication with a pressure reference source (16). The injection pressure sensor (10) also includes a sensor body (20) and a plunger element (26). If the injection pressure sensor (10) experiences high fluid pressures, the sensor element (14) can fail and fluid can escape past the sensor element (14). When the sensor element (14) fails, the plunger element (26) moves from an inactive position (28) into an active position (32). When the plunger element (26) is in the active position (32), fluid is generally prevented from escaping the sensor body (20).

Abstract: An injection pressure sensor (10) intended for use with a fluid source (12). The injection pressure sensor (10) has a sensor element (14). and a tube member (18). The tube member (18) creates a fluid pathway (20) between the fluid source (12) and the sensor element (14). The tube member (18) contains a collapsible portion (22), such that when the tube member (18) is bent, the fluid pathway (20) is generally closed.

Abstract: A delivery chute flow control device is disclosed. The device has a body portion which mates with the remainder of the delivery chute. Affixed to one end of the body portion is a rotatable door which is used to control the flow of material. A locking mechanism is provided as a way of securing the door in a fixed position.
