Cartridge assembly
First Claim
1. A cartridge assembly, comprising:
- a housing including a flow cell chamber to receive a flow cell;
a well plate having liquid wells to receive amounts of liquids, the well plate including a valve station, a pump station and a fluidics analysis station, the well plate including channels fluidly connected with the wells, the valve station, pump station and fluidics analysis station;
a pump assembly provided on the well plate at the pump station, the pump assembly to manage fluid flow through the channels between the pump station and the fluidics analysis station; and
a rotary valve assembly positioned on the well plate at the valve station, the rotary valve assembly including a rotor shaft and a rotor valve positioned to rotate about a rotational axis and to selectively couple the wells to the pump station,the rotor shaft having a distal end exposed through the housing,the rotor shaft including a dual spline configuration at the distal end thereof, the dual spline configuration having first and second sets of splines, the first set of splines forming a drive interface, the second set of splines forming a position encoding interface.

Abstract
A cartridge assembly that comprises a housing, including a flow cell chamber to receive a flow cell, and a well plate having liquid wells to receive desired amounts of liquids. The well plate includes a valve station, a pump station and a fluidics analysis station, and channels associated therewith. A pump assembly to manage fluid flow through the channels between the pump station and the fluidics analysis station. A rotary valve assembly that includes a rotor shaft and rotor valve positioned to rotate about a rotational axis and to selectively couple the wells to the pump station. The rotor shaft includes a dual spline configuration at the distal end thereof. The dual spline configuration has first and second sets of splines. The first set of splines forms a drive interface and the second set of splines forms a position encoding interface.
