The fastener installation apparatus and method of the present invention include a housing and a moveable body at least partially within the housing. The moveable body defines a plurality of openings and is fixably attached to at least one piston, which is in moveable contact with the housing. First and second cavities are defined on opposite sides of the piston and respective openings in the moveable body are in communication with opposite sides of the piston. In addition, a valve directs a fluid through the appropriate openings in the moveable body and into the first cavity or the second cavity, as desired, which, in turn, alternately extends and retracts the moveable body relative to the housing. A jaw extends from the housing in alignment with the moveable body, such that the jaw and the moveable body cooperate to install a fastener upon extension of the moveable body.

1. A fastener installation apparatus, comprising:a housing; a moveable body at least partially within said housing and adapted to move in a lengthwise direction through said housing, wherein said body defines a plurality of openings; at least one piston fixedly attached to said moveable body and in moveable contact with said housing to thereby define first and second cavities on opposite sides of the piston and separated from one another in the lengthwise direction by the piston, wherein said moveable body defines respective openings in communication with the first and second cavities that are separated from one another in the lengthwise direction on opposite sides of the piston; a valve that is capable of alternately directing a fluid through a respective opening defined by the moveable body and into the first cavity and then through another respective opening defined by the moveable body and into the second cavity such that the moveable body is capable of being alternately extended and retracted in the lengthwise direction relative to the housing; and a jaw extending from said housing in alignment with said moveable body such that the jaw and moveable body cooperate to install a fastener upon extension of the moveable body. 2. The fastener installation apparatus of claim 1, wherein said jaw is also in alignment with a fastener having a head and a shaft, wherein said jaw and the moveable body are spaced apart while the moveable body is retracted so as to be capable of receiving a portion of the structure that defines a hole to receive the shaft of the fastener in the space between the jaw and the moveable body.3. The fastener installation apparatus of claim 2, wherein said moveable body defines another opening capable of receiving the shaft of the fastener.4. The fastener installation apparatus of claim 3, wherein said movable body comprises an end cap, and wherein the end cap is aligned with said jaw and at least partially defines the opening that is capable of receiving the shaft of the fastener.5. The fastener installation apparatus of claim 4, wherein the end cap is made of a non-marring material.6. The fastener installation apparatus of claim 1, wherein said jaw is rotatably connected to said housing.7. The fastener installation apparatus of claim 1, wherein said jaw is detachably connected to said housing.8. The fastener installation apparatus of claim 7, wherein said jaw is one of a plurality of jaws capable of being detachably connected to said housing.9. The fastener installation apparatus of claim 1, wherein the piston is in substantially air-tight contact with said housing.10. The fastener installation apparatus of claim 1, further comprising at least one partition fixedly attached to said housing and in moveable contact with said moveable body, each partition positioned within said housing relative to a respective piston to define one of the first and second cavities therebetween.11. The fastener installation apparatus of claim 10, wherein said at least one piston comprises a plurality of pistons fixedly attached to said movable body and spaced apart from one another, and wherein said at least one partition comprises a plurality of partitions fixedly attached to said housing, said plurality of partitions being spaced apart from one another and interdigitated with respect to said plurality of pistons.12. The fastener installation apparatus of claim 11, wherein said housing, said plurality of partitions and said plurality of pistons cooperate to define respective first and second cavities on opposite sides of each piston, and wherein said moveable body defines a plurality of openings with at least one opening in communication with each of the first and second cavities.13. The fastener installation apparatus of claim 12, wherein said moveable body defines the openings such that all openings in communication with a first cavity are in fluid communication and such that all openings in communication with a second cavity are in fluid communication.14. A method for installing a fastener, comprising:at least partially inserting the fastener in a hole defined by a structure; positioning a jaw proximate a first end of the fastener; positioning a moveable body defining at least one opening proximate a second end of the fastener on an opposite side of the structure from the jaw; moving the moveable body toward the jaw such that the moveable body is in operable contact with the structure and such that further movement of the moveable body causes the jaw to force the fastener further into the hole; and receiving the second end of the fastener within the opening defined by the moveable body in response to movement of the moveable body such that further movement of the moveable body toward the jaw causes the fastener to be inserted further into the opening defined by the moveable body. 15. The method of claim 14, wherein positioning the jaw comprises aligning the jaw with the first end of the fastener.16. The method of claim 14, wherein positioning the moveable body comprises aligning the opening defined by the body with the second end of the fastener.17. The method of claim 14, wherein moving the moveable body toward the jaw comprises controlling movement of the moveable body relative to a housing at least partially surrounding the moveable body.18. The method of claim 17, wherein moving the moveable body comprises moving the moveable body in a lengthwise direction through the housing, and wherein controlling movement of the moveable body relative to the housing comprises controllably and alternately directing a fluid into one of first and second cavities defined within the housing and separated from one another in the lengthwise direction on opposite sides of a piston that is fixedly attached to the moveable body and in moveable contact with the housing.19. The method of claim 18, wherein moving the moveable body toward the jaw further comprises filling the first cavity disposed on an opposite side of the piston in the lengthwise direction from the structure with fluid.20. The method of claim 18, further comprising moving the moveable body away from the jaw after forcing the fastener into the hole by filling the second cavity disposed in the lengthwise direction on a side of the piston facing the structure with fluid.21. The method of claim 18, wherein controllably directing the fluid comprises controlling the fluid flow to the first cavity via a pneumatic valve and at least one opening defined by the moveable body that direct the fluid flow to a first side of the piston.22. The method of claim 18, wherein controllably directing the fluid comprises controlling the fluid flow to the second cavity via a pneumatic valve and at least one opening defined by the moveable body that direct the fluid flow to a second side of the piston.23. The method of claim 14, further comprising rotating the jaw about the moveable body.24. The method of claim 14, further comprising detachably connecting the jaw to a housing that at least partially surrounds the moveable body such that one jaw may be detached and another jaw may be attached to the housing.
