A hydraulic pump for use in a pump assembly of a railway track lubricating system includes a housing defining an intake chamber having an intake port, an outlet channel leading to an outlet port, a gear chamber containing interengaged gears, a discharge port having a discharge port, a window opening between the gear chamber and the discharge chamber, and a double head piston having a first head in the intake chamber, a second head in the discharge chamber, and a spring for biasing the piston to a first position where the first head is spaced a maximum from a wall between the intake chamber and the discharge chamber. The outlet port has a smaller cross section than the outlet channel so that checked charged deliveries of hydraulic fluid into the intake chamber will cause the piston to move from its first position to a second position and force grease out of the discharge chamber through the discharge port. The pump assembly includes the rotociprocating pump and a hydraulic motor connected to operate the rotociprocating pump based on flow thereto of hydraulic fluid from the outlet port of the pump.

Rotociprocating pump

A device for lubricating a track or a rail that is adapted to be mounted to a wheeled vehicle. The device includes a frame member adapted to be mounted to the vehicle and an arm pivotally attached to the frame member. A roller, which is adapted to ride on the rail, mounts to the arm and receives a guide. A lubricating nozzle attaches to the guide.
