Abstract: The present invention presents various novel approaches to solving the problems inherent in measuring biological pressures in high pressure systems. Thus, to protect a pressure transducer exposed to fluid flows at higher pressures than its overpressure rating, a novel valve is used that closes a protected leg in which the transducer is located. The various exemplary embodiments of such valves each have a high pressure input, one or more low pressure inputs, and an output. In operation, when a high pressure fluid flow occurs at a high pressure input, such valves automatically close the low pressure inputs. Alternatively, a novel transducer system is presented, which automatically limits the effective pressure sensed by a transducer to a certain maximum.

To overcome the strain issues, the bus has the control lever mounted therein is mounted using a conical face and also conical part of the front wall of the cylinderal housing.

Abstract: A multi-channel valve having a valve seat, a valve seal, and valve seal housing. The assembly of the apparatus creates a plurality of inlet, exit, and cross channels enclosed by elastomeric portions of a valve seal. The elastomeric portions of the valve seal create bounded distensible chambers. Pressure exerted by a fluid in excess of the cracking pressure of the seal tends to distend portions of the elastomeric seal and allow flow through and into the chambers. When inflow pressure falls, the elastic rebound of the elastomeric portions of the seal tends to expel fluid from the valve without backflow. Cross channel capacity allows mixing of the fluids. The plurality of, and differentials between, chambers allows one fluid to completely purge the valve of other fluids. The valve may be configured with additional backflow prevention capacities, such as channel variations, secondary elastomeric members, and variations in primary membrane properties.
