Transmission valve manifold and method of manufacturing a transmission valve manifold
First Claim
1. A transmission valve manifold comprising:
- a single, unitary, monolithic, manifold body, the manifold body having a plurality of fluid passageways, and a plurality of fluid chambers, each fluid chamber being configured to receive one of a cylinder body, a solenoid valve, or a spool valve;
wherein a first one of the fluid passageways follows a path that extends along three axes through an interior of the manifold body to connect at least one of the fluid chambers with at least one other one of the fluid chambers, the first one of the fluid passageways extending through a second one of the fluid passageways within the interior of the manifold body; and
wherein the first one of the fluid passageways is not in fluid communication with the second one of the fluid passageways at a location where the first one of the fluid passageways extends through the second one of the fluid passageways.

Abstract
A transmission valve manifold can include a single, unitary, monolithic, manifold body (14). The body (14) can have a plurality of fluid passageways (550, 554, 558, 562, 566) and fluid chambers (130a-d, 134a-d, 326a-f, 338a-c, 510a-h). Each chamber (130a-d, 134a-d, 326a-f, 338a-c, 510a-h) can receive one of a cylinder body (142a-d, 146a-d), solenoid valve (22a-f), or spool valve (30a-h). A first passageway (550, 554, 558, 562, 566) can follow a path that extends along three axes through an interior of the body (14) to connect at least one of the chambers (130a-d, 134a-d, 326a-f, 338a-c, 510a-h) with at least one other chamber (130a-d, 134a-d, 326a-f, 338a-c, 510a-h). The first passageway (550, 554, 558, 562, 566) can overlap a second passageway (550, 554, 558, 562, 566) within the body (14). The body (14) can be manufactured by laser sintering of successive layers of laser sinterable material (1022).
