An electric seat assist device having a seat pivotally secured to a base. One or more cam members extend in generally opposing relationship from the seat and base and are seated on one or more sets of rollers which are linearly adjusted to raise and lower the seat by a drive member which is pivotally mounted relative to the base and the rollers of the seat assist device. Stroke detectors are used to control motor drivingly connected to the drive member after being activated to initiate raising or lowering of the seat.

Electric lifting cushion

The present invention provides a supplementary pressure regulator that can be used with conventional single or multi-stage pressure regulators. It may also conveniently be used with a novel two stage balanced pressure regulator to form a three-stage vacuum demand pressure regulation system which may be used to regulate the pressure of compressed gases used as fuel in engines, such as natural gas used in natural gas powered vehicles. The pressure regulator of the present invention is a robust, compact, high flow, low droop, low pressure drop, low set-point drift and low creep regulator which is suitable for both OEM and after market use. It is particularly useful in mono-, bi-, and dual fuel engine applications.

Three stage gas pressure regulator

The present invention provides an improved two-stage pressure regulators for various compressed gases, and more particularly to pressure regulators used for gaseous fuels such as compressed or liquified natural gas. The pressure regulator of the present invention is a robust, compact, high flow, low droop, low pressure drop and low creep regulator which is suitable for both OEM and aftermarket use. It can be used by itself, or with an optional third stage to provide a three stage regulator such as the atmospheric (or zero pressure differential) types commonly used to regulate the fuel pressure for gaseous carburetion systems. It is particularly useful in mono-, bi-, and dual fuel engine applications. The two stage regulator of the present invention consists of a single base (the 'regulator base') upon which are mounted all of the components of the regulator, including the first and second stage regulator spring towers, a pressure relief valve (or PRV) spring tower, a filter assembly, a high pressure solenoid-activated valve, and an optional cylinder pressure sender. Channels provided in the base, for example by machining, permit the flow of coolant or other fluid through the base to control the temperature of the pressure regulator, and thus the outlet temperature of the gas flowing through it.
