Title:
液圧回路用ディスクパックバルブアセンブリ
Document Type and Number:
Japanese Patent JP4139217
Kind Code:
B2
Abstract:
An integrated assembly (58,72) form a parallel arrangement of a relief valve (60,74), an orifice (62,76) and a check valve (64,78). A body (84) has a first flange (85) with a perimeter surface that engages a wall of a bore (82) in which the assembly fits. An number of apertures (87) extend through the flange. A second flange (93) extends from the body and has an annular lip (94) which defines a recess cavity (95) at one end (81) of the body. The body has a passage (96,97) extending between the other end (83) and the recess. A check valve member (64) is slidably mounted on the body and closes the aperture (87) when pressure adjacent the second end is greater than pressure adjacent the first end. A plurality of disks (101) are mounted on the body and engage the annular lip (94) to form an orifice (62) between the disks and the lip. The disks disengage the annular lip when pressure in the bore (96) adjacent to the second end is greater than predefined level.
