An improved pump is disclosed comprising a pump body having a piston supported by a base from a fluid reservoir. A trigger extends a between a first portion and a second portion with an intermediate trigger pivot mounted relative to the base. A cam and a cam follower couples the first portion of the trigger with the piston for enabling a depression of the second portion trigger to move the piston to spray fluid from the pump body orifice. 1. An improved pump dispenser for discharging a fluid from a fluid reservoir , comprising:a pump body having a pump body orifice;a piston slidably disposed in said pump body;a base supporting said pump body relative a the fluid reservoir;a trigger extending a between a first portion and a second portion;a base pivot pivotably mounting said trigger relative to the base; anda cam and a cam follower coupling said first portion of said trigger with said piston for enabling a depression of said second portion trigger to move said piston to spray fluid from said pump body orifice.2. An improved pump dispenser as set forth in claim 1 , wherein said base secures said pump body to said base enabling the interchange of different pump bodies.3. An improved pump dispenser as set forth in claim 1 , including a hood for covering the pump body for changing the appearance of the pump dispenser.4. An improved pump dispenser as set forth claim 1 , including an arm extending from said base; andsaid base pivot mounted on said arm for pivoting said trigger.5. An improved pump dispenser as set forth in claim 1 , wherein said cam is located on said first portion of said trigger and said cam follower is connected to said piston.6. An improved pump dispenser as set forth in claim 1 , wherein said cam is located on said first portion of said trigger; andsaid cam follower disposed on a linkage interconnected to said piston.7. An improved pump dispenser as set forth in claim 1 , including a linkage interconnected to said piston;said cam being located on said ...
