Abstract
Elastomeric bladder assemblies designed for operation at constant pressure to maintain a constant dispensing rate for the contents exhibit a pressure spike shortly before the end of the duty cycle. This pressure spike may be prevented by including within the lumen of the bladder a bolus forming means which prevents the bladder from collapsing to a cylindrical configuration.
