  • a. a valve shaft having an inlet port, for allowing fluid inflow in a first direction towards the plunger, the valve shaft oriented within the pump housing such that a first end of the valve shaft is proximal to the plunger and a second end of the valve shaft is distal to the plunger; and

    b. a valve head attached to the first end of the valve shaft, the valve head having at least one outlet port for allowing fluid outflow in a second direction away from the plunger; and
