Write down the purpose of using cheek valve in a hydraulic circuit. Draw a neat sketch of cheek valve. Draw any hydraulic circuit using cheek valve.

 Cheek valves are the most commonly used and simplest types of direction control valve. The cheek valve is a two way valve. The check valves are used 

  1. To allow the free flow in only one direction.
  2. To prevent any flow in the other direction
Since check valve block the reverse flow of the fluid they are also know as non-return valve.

What are the types of the gear pumps? With neat sketch discuss construction working of any type of gear pump.

 There are four types of gear pump External Gear Pump Internal Gear Pump Screw Pump Lobe Pump The basic principle of external gear pump is that a pair of gears being driven by an external means. The gear motion generates suction at inlet by creating a partial vacuum which causes fluid to be drawn into the pump housing. The fluid is drawn through the pump and is displaced as the teeth mesh on the outlet side. Construction: External gear pump have two mating gear that are turned in a closely fitted casing. Each gear is mounted on a shaft which is supported on bearing in the end covers. In this drive shaft is coupled to the prime mover. Two ports inlet and outlet are provided directly on the opposite side of the mesh point of the gears. The larger and straight ports are preferred for better performance. The driving shaft is usually connected to the upper gear of the pump. The rotation of the driver gear cause the follower gear to turn. Operation: When the pump starts rotating the rota...

With neat sketch explain the working of a pressure compensated flow control valve and pressure unloading valve.

  Oil from the pump flows through the flow central valve and the flow is restricted. The approach to the adjustable restrictor is also through the pressure compensator spool. There is enough passage and space around the compensator for the oil to reach the restrictor. Let us say the pump flow is 221/min and the restrictor is adjusted to allow 101/min. There is a balance flow of 121/min which will be building up pressure in the pipe line P. The load pressure from port A of the cylinder is felt on the outlet of the flow control valve. If the spring rating is 1 bar and the load pressure at port A is 50 bar then the pressure felt on the left-hand side of the pressure compensator is 51-bar. The pressure on the right side of the compensator slowly builds-up. When this pressure reaches a pressure level just above 51-bar, the pressure compensator moves towards the left compressing the spring. In moving the passage to the restrictor is narrowed by the landing of the pressure compensator. Th...

State the sequence of events in system of design cycle ( General procedure of machine design).

  General Procedure in Machine Design: In designing a machine component there is no rigid rule. The problem may be attempted in several ways. However the general procedure to solve a design problem is as follows:  Recognition of need: First of all make a complete statement of the problem indicating the need aim or purpose for which the machine is to be designed.                                                                     Synthesis (Mechanisms): Select the possible mechanism or group of mechanisms which will give the desired motion.                                                                            ...
