Relief valve mechanism for an oil pump
First Claim
1. A relief valve mechanism for an oil pump comprising;
- a body having a first hole;
a spring housed in the body and adapted to apply biasing force to a relief valve in response to contraction of the spring;
a first opening connected to the first hole of the body;
the relief valve adapted to close the first opening in response to the biasing force of the spring and adapted to open the first opening against the biasing force in response to pressure of fluid from the oil pump applied to one end of the valve; and
means for sensing a temperature positioned at the spring.

Abstract
A relief valve mechanism for an oil pump includes a body having a first hole, a spring housed in the body adapted to apply biasing force to a relief valve in response to contraction of the spring, a first opening connected to the first hole of the body, a relief valve adapted to close the first opening in response to the biasing force of the spring and adapted to open the first opening against the biasing force in response to pressure of fluid from the oil pump applied to one end of the valve means and means for sensing a temperature at a the spring at a side of a valve or at an opposite side to the valve. The means for sensing the temperature is altered in an axial direction of the spring.

8. A method of releasing fluid comprising:
-
pumping fluid by an oil pump along a first passage;
directing the fluid pumped by the oil pump along a second passage;
releasing at least a portion of the fluid to a valve relief mechanism; and
moving a relief valve of the valve relief mechanism against a biasing force of a spring so as to release at least the portion of the fluid to the first passage. - View Dependent Claims (9, 10)
