A fluid pump for a linear actuator, comprising: a housing defining an inlet port configured for fluid communication with a fluid reservoir and first and second outlet ports (84, 86) configured for fluid communication with first and second portions (70, 72) of a fluid chamber formed on opposite sides of a piston disposed within the fluid chamber; a driven pump element (88, 90) disposed within the housing; a first check valve configured to control fluid flow between the driven pump element (88, 90) and the first outlet port; a second check valve configured to control fluid flow between the driven pump element (88, 90) and the second outlet port; a first shuttle disposed between the first check valve and the second check valve and movable along a shuttle axis extending through the first check valve and the second check valve responsive to fluid pressure in the housing; wherein the first check valve includes a valve member movable between a closed position and an open position defining a fluid flow path between the driven pump element (88, 90) and the first outlet port and means for limiting movement of the first shuttle in a first direction along the shuttle axis towards the first check valve, rotation of the driven pump element (88, 90) in a first rotational direction establishing a first fluid pressure causing the valve member to move from the closed position to the open position and rotation of the driven pump element (88, 90) in a second rotational direction establishing a second fluid pressure causing the first shuttle to move in the first direction along the shuttle axis and move the valve member from the closed position to one of the open position and an intermediate position between the closed position and the open position responsive to a position of the limiting means along the shuttle axis wherein the first check valve further includes a body supported within the housing and characterized in that the first check valve further includes a pedestal supported within the body and supporting the limiting means, the pedestal movable within the body along the shuttle axis to adjust the position of the limiting means along the shuttle axis. a housing defining an inlet port configured for fluid communication with a fluid reservoir and first and second outlet ports (84, 86) configured for fluid communication with first and second portions (70, 72) of a fluid chamber formed on opposite sides of a piston disposed within the fluid chamber; a driven pump element (88, 90) disposed within the housing; a first check valve configured to control fluid flow between the driven pump element (88, 90) and the first outlet port; a second check valve configured to control fluid flow between the driven pump element (88, 90) and the second outlet port; a first shuttle disposed between the first check valve and the second check valve and movable along a shuttle axis extending through the first check valve and the second check valve responsive to fluid pressure in the housing; wherein the first check valve includes a valve member movable between a closed position and an open position defining a fluid flow path between the driven pump element (88, 90) and the first outlet port and means for limiting movement of the first shuttle in a first direction along the shuttle axis towards the first check valve, rotation of the driven pump element (88, 90) in a first rotational direction establishing a first fluid pressure causing the valve member to move from the closed position to the open position and rotation of the driven pump element (88, 90) in a second rotational direction establishing a second fluid pressure causing the first shuttle to move in the first direction along the shuttle axis and move the valve member from the closed position to one of the open position and an intermediate position between the closed position and the open position responsive to a position of the limiting means along the shuttle axis wherein the first check valve further includes a body supported within the housing and characterized in that the first check valve further includes a pedestal supported within the body and supporting the limiting means, the pedestal movable within the body along the shuttle axis to adjust the position of the limiting means along the shuttle axis.
