Abstract
A relief valve assembly, comprises: a relief valve; a valve housing including a valve path along which the relief valve can slide; a relief inflow portion formed on one end of the valve housing; and relief discharge portions formed at an intermediate location of the valve path of the valve housing and provided with small aperture portions axed large aperture portions formed in communication with one another. A side wherein the relief discharge portions are provided with the small aperture portions is the side near the relief inflow portion.
Claims17
A relief valve assembly, comprising:
- a valve housing defining a valve path therein;
- a relief valve slidable along the valve path;
- a relief inflow portion formed at one end of the valve housing;
- and
- relief discharge apertures formed in an intermediate region on a wall of said valve housing, each of said relief discharge aperture comprising at least one small aperture section and a large aperture section in communication with one another;
- wherein
- said large aperture section is in a substantially rectangular shape as seen in a radial direction perpendicular to the valve path;
- and
- said at least one small aperture section is formed on a side of the rectangular shape that faces said relief inflow portion.
A relief valve assembly, comprising:
- a valve housing defining a valve path therein;
- a relief valve slidable along the valve path;
- a relief inflow portion formed at one end of the valve housing;
- and
- relief discharge apertures formed in an intermediate region on a wall of said valve housing, each of said relief discharge aperture comprising at least a small aperture section and a large aperture section in communication with one another;
- wherein
- said large aperture section is an elongated slot having a substantially uniform width, as measured in a direction of the valve path, and extending circumferentially of said valve housing in a plane substantially perpendicularly to the valve path;
- said at least one small aperture section is formed on a side of the elongated slot that faces said relief inflow portion;
- and
- at least one of said relief discharge apertures comprises two distinct said small aperture sections formed adjacent to two longitudinally opposite ends of the associated large aperture section.
A relief valve assembly, comprising:
- a valve housing defining a valve path therein;
- a relief valve slidable along the valve path;
- a relief inflow portion formed at one end of the valve housing;
- and
- relief discharge apertures formed in an intermediate region on a wall of said valve housing, each of said relief discharge aperture comprising at least one small aperture section and a large aperture section in communication with one another;
- wherein a length of said relief discharge aperture, as measured circumferentially of said housing in a plane substantially perpendicular to the valve path, changes abruptly at a separation line between said small and large aperture sections.
