摘要 |
<p>A check valve assembly for a clutch, including: an annular-shaped ring element including a first portion with: a first channel wholly enclosed by the first portion; a first through-bore between a radially inner surface of the first portion and the first channel; and a second through-bore between a radially outer surface of the first portion and the first channel. The assembly includes a first pressure regulating assembly at least partially disposed within the first channel and including: a spool axially displaceable within the first channel and including a space enclosed by the spool; a first ball disposed within the space and the first channel; and a first spring engaged with the spool. The spool is arranged to axially displace in response to hydraulic pressure at the first through-bore and axial force applied by the first spring to displace the first ball to block or unblock flow between the first and second through-bores.</p> |
