Japanese Patent JP7146111
Kind Code:
B2
Abstract:
A valve is provided for use with liquid chromatography where liquid is provided to the chromatographic analysis equipment at more than one pressure, including up to ultra-high pressures. High and higher pressure operation are provided by application of force by an internal spring while avoiding wear of components by permitting higher pressure operation by mechanical engagement of an internal element to cause the internal spring to increase the force applied to the rotor, without the addition of external additional loading in the high pressure operation.
