Vibratory Motor Components
(1) End Cap. (2) Port plate. (3) Cylinder block. (4) Piston. (5) Shaft. (6) Flushing shuttle spool. (7) Shim. (8) Flushing relief valve.
(9) Fixed swashplate. (10) Housing.
The vibratory motor is a fixed displacement hydraulic motor.
Oil flows to the motor and from the motor through hoses
attached to the end cap (1).
High pressure oil from the pump enters the motor through the
end cap (1). The oil will pass through the port plate (2) and the
oil will act on the piston (4). Piston (4) is one of seven pistons
in the assembly of the cylinder block (3).
As the pistons react to the high pressure oil, the cylinder block
(3) and the pistons (4) rotate as an assembly. The cylinder
block (3) is splined to the shaft (5). Rotating torque is
transferred to the shaft (5). The displacement of the motor is
controlled by the angle of the fixed swashplate (9). The
nonadjustable swashplate angle is machined into the motor
