FLUID AND POWER PROVISION APPARATUS
DRIVE
December 31, 2025
A fluid and power provision apparatus (10) is provided. The apparatus (10) includes a power provision device (90) and a pump assembly (100). The pump assembly (100) includes a motor (150), a transmission system (200), a piston assembly (300), and a collar assembly (320). The piston assembly (300) includes a piston sleeve (310), a piston (302), and a piston arm (304) operably coupled to the piston (302) and the transmission system (200) to transmit energy from the motor (150) to articulate the piston (302) within the piston sleeve (310). The collar assembly (320) forms a collar plenum (314), a first flowpath (324), and a second flowpath (326). The piston sleeve (310) extends at least in part into the collar plenum (314). The first flowpath (324) extends in fluid communication from the collar plenum (314) to a fluid supply outlet. The second flowpath (326) extends in fluid communication from an interior (22) of the apparatus (10) to the first flowpath (324).
