Abstract

An elastomeric biasing unit for a manually operated dispensing pump of the type including a hollow, stationary piston and reciprocable piston cylinder coaxially disposed about the piston and cooperating therewith to define a variable volume pump chamber. The biasing unit, which urges the piston cylinder outward to a position of maximum pump chamber volume, has an open end in operative association with the piston cylinder and a generally closed end, providing a component of the inlet check valve, in operative association with the piston.
