PISTON GROOVE [3 records]

Record 1 2008-03-04

English

Subject field(s)
  • Aircraft Systems
OBS

The double-action hydraulic hand pump is used in some older aircraft and in a few newer systems as a backup unit. Double-action hand pumps produce fluid flow and pressure on each stroke of the handle. The double-action hand pump consists essentially of a housing which has a cylinder bore and two ports, a piston, two spring-loaded check valves, and an operating handle. An O-ring on the piston seals against leakage between the two chambers of the piston cylinder bore. An O-ring in a groove in the end of the pump housing seals against leakage between the piston rod and housing.

PHR

Hydraulic hand pump.

PHR

Ground service hand pump.
