A compact fluid dispenser for use in controllably dispensing fluid medicaments and a cooperating reservoir fill assembly for controllably filling the fluid reservoir of the fluid dispenser. The fluid dispenser component includes a novel stored energy source in the form of an expandable, elastomeric member of unique construction that provides the force necessary to continuously and substantially uniformly expel fluid from the reservoir of the dispenser component. The fluid dispenser component further includes a fluid flow control assembly that filters and precisely controls the flow of the medicament solution from the reservoir of the dispenser container.
