Inventor: UUSKALLIO ARVO F
IPC: F02M1/16
Filed: 1986-05-02
Granted: 1992-02-18
Abstract: Abstract of the Disclosure A wet priming mechanism for small internal combustion engines.  A priming line connects the main fuel line leading to the engine and the intake port to the cylinder.  A manual bulb-type priming pump is located in the priming line and through operation of the pump, fuel is drawn from the main line and is dis-charged directly to the cylinder.  Located at the dis-charge end of the priming line is a restrictor assembly which defines a small unobstructed orifice.  The ori-fice is sized so that air will be freely discharged from the priming line by operation of the pump without resistance, but provides a substantial resistance to the flow of fuel.  Through operation of the priming bulb, a measured amount of fuel can be injected into the engine to aid in starting.

Abstract: ABSTRACT OF THE DISCLOSURE           A load-carrying vehicle is disclosed which has a chassis over which a load-carrying bucket or platform is fixed and which is, itself, mounted on a caterpillar drive.  A motor assembly is mounted at the front of the chassis and the latter further has a bridge structure located ahead of the motor assembly and connected to the chassis while spanning a steering wheel.          The latter is mounted on a steerable support actuated by a steering lever which projects rearwardly from the bridge structure over the motor assembly and over the load-carrying bucket or platform.  A power transmission connects the motor assembly to the steering wheel and to the caterpillar drive so that the two may be operated simultaneously.
