Abstract
A valve assembly includes a plate defining a wall of a housing and a valve component included in the housing. A position of the valve component sets a state of the valve assembly. A channel is defined through the wall of the housing. A channel groove is defined along a wall of the channel. A sensor housing includes a sensor detecting a state of the valve assembly. A sensor groove is along the sensor housing. A seal cooperates with both the channel groove and the sensor groove when the sensor housing is seated in the channel to both create a pneumatic seal between the sensor housing and the wall of the channel and retain the sensor housing in the channel.
Claims30
A valve assembly, comprising:
- a plate defining a wall of a housing, a valve component included in the housing, a position of the valve component setting a state of the valve assembly;
- a channel defined through the wall of the housing;
- a channel groove defined in a wall of the channel;
- a sensor housing including a sensor detecting the state of the valve assembly;
- a sensor groove along the sensor housing, a diameter of the sensor housing at a first end of the sensor groove being substantially equal to a diameter of the sensor housing at a second end of the sensor groove, the first and second ends being at opposite ends of the sensor groove along the sensor housing, and the sensor housing is substantially frusto-conically shaped along a portion of the housing adjacent to and extending away from the first end of the sensor groove;
- and
- a seal cooperating with both the channel groove and the sensor groove when the sensor housing is seated in the channel to both create a pneumatic seal between the sensor housing and the wall of the channel and retain the sensor housing in the channel.

A sensor, comprising:
- a housing around the sensor, the housing being sized to be received in a channel of a valve assembly;
- and
- a sensor groove along the sensor housing sized to receive a seal, the seal also being received in a channel groove in the channel and cooperating with both the sensor groove and the channel groove for creating a pneumatic seal between the seal and a wall of the channel and retaining the sensor housing in the channel, a diameter of the sensor housing at a first end of the sensor groove being substantially equal to a diameter of the sensor housing at a second end of the sensor groove, the first and second ends being at opposite ends of the sensor groove along the sensor housing, and the sensor housing is substantially frusto-conically shaped along a portion of the housing adjacent to and extending away from the first end of the sensor groove.
A valve assembly, comprising:
- a valve housing;
- a shuttle included in the housing, a position of the shuttle setting a state of the valve assembly;
- a channel defined through the valve housing;
- a circular channel groove defined in a wall of the channel;
- a sensor housing, including a sensor detecting the position of the shuttle, sized to be received in the channel;
- a circular sensor groove along an exterior surface of the sensor housing, a diameter of the sensor housing at a first end of the sensor groove being substantially equal to a diameter of the sensor housing at a second end of the sensor groove, the first and second ends being at opposite ends of the sensor groove along the sensor housing, and the sensor housing is substantially frusto-conically shaped along a portion of the housing adjacent to and extending away from the first end of the sensor groove;
- and
- an o-ring cooperating with both the channel groove and the sensor groove when the sensor housing is received in the channel to both create a pneumatic seal between the seal and the wall of the channel and retain the sensor housing in the channel.
5 more elements
A method of assembling a valve assembly, the method comprising:
- positioning an o-ring in a channel defined in a housing of the valve assembly;
- inserting a sensor housing, including a sensor, into the channel so that the sensor housing engages the o-ring;
- seating the o-ring in a channel groove in a wall of the channel;
- seating the o-ring in a sensor groove, along the sensor housing, a diameter of the sensor housing at a first end of the sensor groove being substantially equal to a diameter of the sensor housing at a second end of the sensor groove, the first and second ends being at opposite ends of the sensor groove along the sensor housing, the sensor housing is substantially frusto-conically shaped along a portion of the housing adjacent to and extending away from the first end of the sensor groove, and once the o-ring is seated in both the channel groove and the sensor groove, the o-ring creating a pneumatic seal between the sensor housing and the wall of the channel and retaining the sensor housing in the channel.
