Abstract: A high pressure pump including a pump body, a pump housing within which at least part of the pump body is located, a gallery defined between the pump body and the pump housing, the pump body having a pump outlet which communicates with the gallery, and the pump housing having an outlet port which communicates with the gallery, and a filler located within the gallery, the filler being located at least in the part of the gallery most remote from the pump outlet.

Abstract: A drive arrangement comprising a drive shaft, a clutch arrangement operable, upon axial movement of the drive shaft occurring, to interrupt drive to the drive shaft, an axially movable interrupt shaft, a gear arrangement whereby the interrupt shaft is driven for rotation by the drive shaft at a speed slower than the rotary speed of the drive shaft, a disconnect device operable to cause axial movement of the interrupt shaft, and a transmission device for transmitting axial movement of the interrupt shaft to the drive shaft.

Abstract: A drive disconnect device for releasably connecting an electrical generator to a drive shaft, the drive disconnect device comprising an output shaft and at least one drive transfer element movable from a first position where it drivingly connects the drive shaft and the output shaft to a second position where the driving connection is removed, wherein operation of the disconnect device causes the electrical generator to become electrically isolated or excitation for the generator to be inhibited.

Abstract: A rotor for a dynamo electric machine comprises a rotor body 12 defining a plurality of poles in the form of limbs 16 around which windings 18 are provided, and a wedge arrangement 20 spanning the space 42 between adjacent limbs 16 and serving to secure the windings 18 in position, and a discharge passage 44 for delivering coolant to the said space.

Abstract: A disconnect mechanism is provided which, upon a suitable trigger event, such as excess temperature causes a camming element 40 having a tapered head 52 to move under the urging of a compression spring 60 such that the tapered head 52 becomes trapped between a rotating element 32 and a support 42. This gives rise to frictional inter-engagement which prevents further rotation of the rotating element 32 and thereby locks the rotating machine against further rotation. This is turn causes the shear region to fail thereby drivingly disconnecting the machine from its prime mover.
