Patent number: 10125872Abstract: Device, system, and method are described directed to seal assemblies with support to reduce seal extrusion under high to very high pressure changes due to repeated piston reciprocating movement. In some examples, concave features are incorporated on the inner and outer edges of support and backup ring elements to support and hug the preceding element and constrain extrusion, as well as utilizing multiple contact points on certain elements in order to reduce friction against the dynamic surface. The seal assemblies described herein can also incorporate bearing surfaces to reduce damage to seal ID due to off-axis floating rod, such as incorporating one or more multi-point contacts to reduce friction.Type: GrantFiled: August 15, 2012Date of Patent: November 13, 2018Assignee: Bal Seal Engineering, Inc.Inventors: Michael Binder, Amin Tariq

Patent number: 9829028Abstract: The present application relates to connectors that use canted coil springs to retain a pin to a housing. The connectors have increased disconnect to connect force ratios. Dual concentric spring configuration allows for an initial locking configuration that can be overcome with higher force and deflection of the second spring. Dual springs in series in a constrained groove can require a high force for connector disconnect, since force vectors may be in a direction relatively close to being along the spring major axis. A curved groove wall can offer resistance to a spring that is required to slide first into the groove in order to allow disconnect.Type: GrantFiled: November 14, 2013Date of Patent: November 28, 2017Assignee: Bal Seal Engineering, Inc.Inventors: Derek Changsrivong, Rick Dawson, Jim Sittler
