摘要

#CMT# #/CMT# The hand pump has a blockable delivery head (1)with an inner locking sleeve (5) forming a cylinder guide. The locking sleeve forms with the piston rod (6) an inner cage (18) to hold a spring (19) which is supported on one side on a base (20) of the sleeve and on the other side on the locking element (21) provided on the piston rod. The locking sleeve forms with the cylinder along the upper section facing the delivery head a guide channel (11) as a guideway for the outer shaft section (12) of the head parallel to the piston rod. #CMT# : #/CMT# The locking sleeve can be inserted through a clamping ring (7) securely seated in the cylinder to form a stop for the outer shaft section . #CMT#USE : #/CMT# AS a dispenser. #CMT#ADVANTAGE : #/CMT# Ensures securely guided movement of delivery head to eliminate canting and jamming to ensure correct delivery . #CMT#DESCRIPTION OF DRAWINGS : #/CMT# Figure shows longitudinal section through pump in rest position 1 : delivery head 5 : inner locking sleeve 6 : piston rod 18 : inner cage 21 : locking element.
