Abstract
An injector apparatus includes a housing () for a cartridge or syringe, a plunger () for cooperating in use with the cartridge or syringe to express successive doses, a dose setting arrangement () to select a dose volume, and a drive mechanism () releasable to advance the plunger in respective predetermined increments of magnitude to express the successive doses. The drive mechanism includes a drive spring () for imparting movement directly or indirectly to the plunger (), and the dose setting arrangement includes a dose setting element () moveable in a dose setting routine to define a magnitude of an increment of movement of the plunger for a given dose. The drive mechanism further includes a clutch arrangement () operable during the dose setting routine to inhibit forward movement of the plunger and/or to isolate the dose setting element from the force of the drive spring.
