The motor housing wall extends along a first axis between a first motor housing end and a second motor housing end. The end cap is disposed at the first motor housing end. The end cap defines a projection having a first portion that extends along the first axis and a second portion that extends along a second axis that is offset from the first axis. The second portion is arranged to receive a valve assembly. ## Claims ### Claim 1 A power pack assembly for a power steering system, comprising: a motor housing having a motor housing wall extending between a first motor housing end and a second motor housing end along a first axis, the motor housing having an end cap disposed at the first motor housing end, the end cap defining a projection extending from the end cap along the first axis, the projection having a first portion defining a first opening that extends along the first axis and a second portion extending from the first portion, the second portion defining a second opening that extends along a second axis; and a valve assembly arranged to be disposed within the second opening. ### Claim 2 (depends on 1) The power pack assembly of claim 1, wherein the second axis that is disposed parallel to and offset from the first axis. ### Claim 3 (depends on 1) The power pack assembly of claim 1, wherein the end cap and the motor housing wall define an interior of the motor housing. ### Claim 4 (depends on 3) The power pack assembly of claim 3, wherein the valve assembly at least partially extends into the interior. ### Claim 5 (depends on 1) The power pack assembly of claim 1, wherein the second opening extends from a first end face of the second portion to a second end face of the second portion. ### Claim 6 (depends on 5) The power pack assembly of claim 5, wherein the second portion includes a retaining feature that is disposed within the second opening. ### Claim 7 (depends on 6) The power pack assembly of claim 6, wherein the retaining feature is disposed between the first end face and the second end face. ### Claim 8 (depends on 6) The power pack assembly of claim 6, wherein the second opening has a first diameter that is disposed between the first end face and the retaining feature. ### Claim 9 (depends on 8) The power pack assembly of claim 8, wherein the second opening has a second diameter that is disposed between the retaining feature and the second end face, the second diameter being less than the first diameter. ### Claim 10 (depends on 1) The power pack assembly of claim 1, further comprising a vent disposed on the end cap. ### Claim 11 (depends on 10) The power pack assembly of claim 10, wherein the vent is disposed between the projection and a first retaining ring extending from the end cap. ### Claim 12 (depends on 1) The power pack assembly of claim 1, further comprising a mechanical housing arranged to be operatively connected to the motor housing, the mechanical housing having a mechanical housing wall extending between a first mechanical housing end and a second mechanical housing end along the first axis, the mechanical housing having an end wall disposed at the second mechanical housing end, the end wall defining an end wall opening. ### Claim 13 (depends on 12) The power pack assembly of claim 12, wherein the end wall opening is proximately aligned with second opening. ### Claim 14 A motor housing provided with a power pack assembly for a power steering system, comprising: a motor housing wall extending along a first axis between a first motor housing end and a second motor housing end; and an end cap disposed at the first motor housing end, the end cap defining a projection having a first portion that extends along the first axis and a second portion that extends along a second axis that is offset from the first axis, the second portion being arranged to receive a valve assembly. ### Claim 15 (depends on 14) The motor housing of claim 14, wherein the end cap defines a first retaining ring that is at least partially disposed about the projection. ### Claim 16 (depends on 15) The motor housing of claim 15, wherein the end cap defines a vent that is disposed between the projection and the retaining ring. ### Claim 17 (depends on 14) The motor housing of claim 14, wherein the second opening extends along the second axis between a first end face of the second portion towards a second end face of the second portion. ### Claim 18 (depends on 17) The motor housing of claim 17, wherein the second portion defines a threaded region that extends between the first end face and a first retaining feature. ### Claim 19 (depends on 18) The motor housing of claim 18, wherein the second portion defines a non-threaded region that extends between the first retaining feature and a second retaining feature disposed proximate the second end face. ### Claim 20 (depends on 19) The motor housing of claim 19, wherein at least one of the first retaining feature and the second retaining feature engages a portion of the valve assembly.
