snubber

[′snəb·ər]
(mechanical engineering)
A mechanical device consisting essentially of a drum, spring, and friction band, connected between axle and frame, in order to slow the recoil of the spring and reduce jolting.

snubber

snubber, 1
1. A component of a vibration isolator that limits the displacement of the isolator in either the vertical or horizontal direction.
2. On a very large expulsion-type fuse, a silencer that reduces the loud noise produced in clearing heavy electrical faults.

snubber

i. A component in a hydraulic or pneumatic actuator that slows down the motion of the piston toward the end of its travel and thus cushions the stopping action of the piston.
ii. A restrictor fitting installed between an oil pressure gauge and the pressure pump. A snubber prevents the indicator from oscillating.

CE] is now clamped to zero due to the snubber diode [D.
In most cases, the pressure transducer is connected to a meter of a recorder that updates at 2 to 3 times/sec; therefore a snubber will not affect it at all.
Figure 3 shows the SHAG series calculated and measured accelerations in gs produced at five locations in the piping system with the snubber and the Seismic Stop support configuration.
These diodes minimize losses in hard switching applications, while maintaining superior soft recovery characteristics to minimize switching noise and eliminate the need for costly snubber circuits.
Every power converter requires a snubber network to keep the flyback energy from either radiating or destroying the switch.
The new platinum devices have a 600V rating and a "soft" recovery current waveshape to reduce or eliminate the need for snubber components.
Soft recovery minimizes ringing to expand the range of conditions under which the diode may be operated without using additional snubber circuitry, while reducing EMI and improving system reliability.
Snubbers irritated Wilde; positioned at the point where the airflow was sonic, they caused large losses.
The series is also suited for use as snubbers, resonators, filters, or DC blocking caps in automotive, medical, industrial, and commercial electronics, including displays, high voltage multipliers, high frequency power converters, and SMPS.

These adjustable choke valve snubbers are typically used to protect pressure gauges from pressure perturbation, surges and fluid hammering, often caused by reciprocating compressors and pumps.
The shell now features redesigned snubbers as well as Venturi ports and extended ear holes which improve ventilation by allowing air circulation and heat dissipation.
