Abstract: Releasable tubing pinch clamps of a generally U-shaped configuration are described. The embodiments include ones that prevent cross-clamping of the tube by various interlocking features on riser portions of the clamp. Methods and molds for making the pinch clamps are also described. The pinch clamp consists generally of a strip that curves so that its ends can be brought together by manually squeezing the strip at its ends which oppose each other as a result of the strip curve. The strip ends contain locking edges or surfaces that cause the strip ends to interferingly engage with each other and lock together. The strip also contains opposing pinching projections that pinch a tube.

Abstract: A valve system includes a spring-biased locking slide plate which extends in an axial direction parallel to and offset from the axis of the valve stem and selectively extends through a base plate mounted to the top of a valve to selectively engage stop tabs on the valve body.

Abstract: A system and device to prevent damage during over-speed condition in a turbo-machine. In one embodiment, the system includes a fluid circuit with a header, which couples to the turbo-machine, and a hydraulic circuit through which fluid evacuates the header to a drain during the over-speed condition. The hydraulic circuit includes a trip header manifold with a pilot element in flow connection with a drain valve element having an actuator to regulate flow of fluid from the header. For example, the pilot element uses a pair of solenoid valves to change pressure of a fluid in the drain valve element and maintains the actuator in a first position to prevent fluid evacuation during normal operating conditions. When over-speed condition is detected, the solenoid valves change state, reducing the pressure of the fluid, permitting the actuator to move to a second position placing the header in flow connection with the drain.

Abstract: An electromagnetic actuator, which is arranged at a position opposing to a hydraulic control valve, has a movable-core chamber for movably accommodating a movable core and an air breathing passage for communicating the movable-core chamber to the atmosphere. An inside opening of the air breathing passage is formed in an inner wall of the movable-core chamber, while an outside opening of the air breathing passage is formed in an outer wall of the actuator, which is in contact with the atmosphere. The outside opening is formed at such a position out of an oil-splashing area, to which oil discharged from an oil-discharge port of the hydraulic control valve is directly splashed. According to the above structure, it is possible to prevent the oil discharged from the oil-discharge port from rushing into the movable-core chamber through the air breathing passage.
