Abstract
PURPOSE:To keep hydraulic power constant by changing the position of a valve spring by a soil spring formed of bimetal corresponding to a temperature. CONSTITUTION:When the temperature rises, the length of a coil spring 15 formed of bimetal is increased, so that a valve spring 8 is pushed toward the right through a retainer 14. Therefore, a valve 9 moves to the right to reduce the area of an escape hole 10, so as to lessen the quantity of oil which is about to escape in large quantities through the escape hole 10, because a temperature rise causes the density and viscosity of oil to lower, whereby pressure P is kept constant. When the temperature falls, the valve spring 8 and the valve 9 are pushed by oil pressure to move to the left, so that the opening area of the escape hole 10 is changed corresponding to the temperature, whereby pressure P of the oil is kept constant.
