A jetting dispenser including an actuator housing, an actuator, a fluid body housing, and a fluid body. The actuator is located in the actuator housing and the fluid body housing is coupled to the actuator housing. The fluid body is coupled to the fluid body housing and includes a fluid inlet in communication with a fluid bore. The fluid body further includes a jetting valve having a movable shaft operatively coupled with the actuator when the fluid body housing is coupled to the actuator housing. The shaft is moved by the actuator to jet an amount of fluid from the fluid bore. The fluid body is capable of being removed from the fluid body housing when the fluid body housing is decoupled from the actuator housing.

1. A jetting dispenser, comprising: an actuator housing,an actuator in the actuator housing,a fluid body housing rotatably coupled to the actuator housing at one end by a hinge and releasably coupled to the actuator housing at another end, the fluid body housing capable of being decoupled from the a
1. A jetting dispenser, comprising: an actuator housing,an actuator in the actuator housing,a fluid body housing rotatably coupled to the actuator housing at one end by a hinge and releasably coupled to the actuator housing at another end, the fluid body housing capable of being decoupled from the actuator housing by rotating the fluid body housing about the hinge, such that the fluid body housing is pivotable between a position in which the fluid body housing is coupled to the actuator housing and a position in which the fluid body housing is decoupled from the actuator housing, anda fluid body comprising a fluid inlet, a jetting valve, and a tappet assembly, the fluid body being retained at least partly in the fluid body housing when the fluid body housing is coupled to the actuator housing, the fluid inlet being in fluid communication with a fluid bore of the jetting valve, the tappet assembly including a movable shaft operatively coupled with the actuator when the fluid body housing is coupled to the actuator housing, the movable shaft being moved by the actuator to jet an amount of fluid from the fluid bore, wherein the fluid body is capable of being removed from the fluid body housing when the fluid body housing is decoupled from the actuator housing. 2. The jetting dispenser of claim 1, wherein the actuator further comprises a piezoelectric unit that lengthens by a first distance in response to an applied voltage, and an amplifier operatively coupled to the piezoelectric unit. 3. The jetting dispenser of claim 1, wherein the fluid body housing is releasably coupled to the actuator housing at the other end with a rotating connector. 4. The jetting dispenser of claim 3, wherein the fluid body housing further comprises a hook flange with which the rotating connector engages to releasably couple the actuator housing with the fluid body housing at the other end. 5. The jetting dispenser of claim 4, wherein a connector housing is rigidly affixed to the actuator housing and wherein a rotating shaft includes the rotating connector and is situated within the connector housing. 6. The jetting dispenser of claim 1, wherein the fluid body housing is releasably coupled to the actuator housing at the other end with a movable pin. 7. The jetting dispenser of claim 6, wherein the movable pin couples the fluid body housing and the actuator housing at the other end by moving within a slot in the fluid body housing. 8. The jetting dispenser of claim 7, wherein a connector housing is rigidly affixed to the actuator housing and includes a spring-biasing element, the movable pin being moved against the spring-biasing element toward the actuator housing to couple or decouple the fluid body housing and the actuator housing at the other end. 9. The jetting dispenser of claim 1, wherein the actuator housing comprises a bore, the tappet assembly being retained in the bore of the actuator housing when the actuator housing and the fluid body housing are coupled. 10. The jetting dispenser of claim 9, wherein the tappet assembly is removable from the fluid body. 11. The jetting dispenser of claim 1, wherein the fluid body housing is configured with a T groove to provide a path for fluid leakage. 12. The jetting dispenser of claim 1, wherein the fluid body housing is rotated downwardly about the hinge.
