Abstract
A silencing choke for a solenoid valve can include a base and a stem configured to be coupled to an armature and can be configured for at least partially reducing or eliminating noise caused by armature bounce. A choke can be configured for limiting maximum flow through an orifice during at least a portion of a valve transition, which can include creating a state of orifice limited flow during the occurrence of armature bounce. A choke can be configured for at least partially reducing cross flow among ports and for limiting a maximum flow rate through at least one flow path of a valve.

A silencing choke for a solenoid valve having a pressure port, a common port, an exhaust port and an armature with a poppet having a first side for selectively engaging a first orifice fluidically between the pressure port and the common port and a second side for selectively engaging a second orifice fluidically between the common port and the exhaust port, the silencing choke comprising:
- a base having a first side and a longitudinally opposite second side;
- a stem coupled to the second side of the base;
- and
- an opening through the base and the stem;
- wherein the silencing choke is configured to be coupled to the armature with the armature disposed through the opening and the first side of the base facing the second side of the poppet.
A solenoid valve, comprising:
- a pressure port;
- a common port;
- an exhaust port;
- an armature with a poppet having a first side for selectively engaging a first orifice fluidically between the pressure port and the common port and a second side for selectively engaging a second orifice fluidically between the common port and the exhaust port;
- and
- a silencing choke coupled to the armature, the silencing choke comprising
- a base having a first side and a longitudinally opposite second side;
- a stem coupled to the second side of the base;
- and
- an opening through the base and the stem;
- wherein the armature is disposed through the opening of the silencing choke;
- and
- wherein the silencing choke is disposed with the first side of the base facing the second side of the poppet.
