Cylinder for linear pump of feeding machine for feeding corn flour and water mixture to palmipeds, has tube including seal formed between piston and outer face of tube, where measuring unit measures position of piston relative to body

摘要

The cylinder (6) has a body (60) with a cylindrical bore (61) closed by a transverse end wall (62) at one end, where the bore receives a piston (64). A piston rod (44) extends between a rear face of the piston and the transverse end wall. A blind axial bore is opened in the rear face of the piston to engage a cylindrical tube (67). The tube includes a continuous seal formed between the piston and an outer face of the tube, and a measuring unit for measuring the position of the piston relative to the body, where the unit includes an element fixed to the piston. An independent claim is also included for a pump.
